[0001] The present invention relates to a glass composition for extracting useful components that can aid in the growth of vegetation and organisms on land and in the ocean, and a method for manufacturing glass powder using the same.

[0002]

[0003] Terrestrial and marine ecosystems are suffering severe damage due to rapid environmental changes and the impact of human activities. This ecosystem destruction leads to problems such as a decline in carbon absorption and storage capacity, disruption of resource cycles, and a decrease in biodiversity. Consequently, ecosystem destruction accelerates climate change and threatens the long-term sustainability of ecosystems.

[0004] In particular, a stable supply of essential nutrients is crucial for the growth and survival of vegetation and various organisms. However, current fertilizers and nutrient supply methods struggle to provide a continuous supply and offer only short-term effects. Consequently, there are limitations to ecosystem restoration and maintaining healthy growth. Furthermore, excessive nutrient supply causes soil and water pollution, which can have a negative impact on the environment.

[0005]

[0006] To solve the aforementioned problem, the present invention aims to provide a glass composition designed so that a specific useful component can be released in a controlled manner according to environmental conditions.

[0007] In addition, the objective of the present invention is to provide a glass composition that can be continuously released at a constant rate without rapid initial dissolution.

[0008] In addition, the objective of the present invention is to provide a durable glass composition capable of functioning effectively in terrestrial and marine environments.

[0009] In addition, the objective of the present invention is to provide a glass composition capable of containing and releasing various useful components to enable appropriate nutrient supply to various vegetation and biological species.

[0010] The objects of the present invention are not limited to those mentioned above, and other unmentioned objects and advantages of the present invention may be understood from the following description and will be more clearly understood by the embodiments of the present invention. Furthermore, it will be readily apparent that the objects and advantages of the present invention can be realized by the means and combinations thereof set forth in the claims.

[0011]

[0012] In the glass composition for the extraction of useful components according to the present invention, useful components capable of aiding the growth of vegetation and organisms on land and in the ocean are added in the form of oxides. The glass composition of the present invention can adequately supply nutrients to vegetation and organisms by extracting the aforementioned useful components.

[0013] Generally, glass materials are typically utilized in industry by enhancing their durability and chemical resistance. However, the glass composition of the present invention is designed to maximize the leaching of specific useful components.

[0014] Inorganic components that can aid in the growth of vegetation and plants, such as P, K, Na, Fe, Mn, Cu, Zn, Ni, B, Mg, and Ca, are well known. The present invention provides a glass containing oxides of the aforementioned components and having the property of being highly soluble in water.

[0015] To this end, the glass composition according to an embodiment of the present invention comprises P2O530 to 75 wt%; one or more of Na2O and K2O at 10 to 45 wt%; one or more of Al2O3 and SiO2 at 0.1 to 10 wt%; and one or more of MgO and CaO at 0.1 to 15 wt%.

[0016] The glass composition of the present invention may further include one or more selected from Fe2O3, MnO2, CuO, ZnO, MoO3, TiO2, and Co3O4 in an amount greater than 0 and less than or equal to 15 weight percent.

[0017] In addition, the glass composition of the present invention may further include B2O3 in an amount greater than 0 and less than or equal to 5 weight percent.

[0018] Here, the Na2O can be added in an amount greater than 0 and less than or equal to 5 weight%, and the K2O can be added in an amount of 10 to 40 weight%.

[0019] In addition, the above Al2O3 may be added in an amount of 0.1 to 5 weight%, and the above SiO2 may be added in an amount greater than 0 and less than or equal to 5 weight%.

[0020] In addition, the MgO can be added in an amount of 0.1 to 7.5 weight%, and the CaO can be added in an amount of 0.1 to 7.5 weight%.

[0021] More preferably, one or more selected from Fe2O3, MnO2, CuO, ZnO, MoO3, TiO2, and Co3O4 may be included in an amount of 0.1 to 10 weight%.

[0022] In addition, the weight ratio of the content of P2O5 and the content of K2O can satisfy the following relationship.

[0023] [Relationship]

[0024] P2O5 content (weight%) / K2O content (weight%) > 1

[0025]

[0026] According to the present invention, useful components released from the glass composition act as a source of nutrients in the soil, promoting the development and growth of plant roots. In particular, the glass composition of the present invention can continuously supply useful components to plants, thereby increasing crop productivity.

[0027] Furthermore, the glass composition of the present invention can supply nutrients necessary for the growth of algae, microalgae, plants, and other organisms inhabiting aquatic environments. The glass composition of the present invention can promote the proliferation of algae and enhance the growth of seaweed and marine organisms. Accordingly, the present invention can contribute to the restoration of marine ecosystems and aquaculture.

[0028] In addition, the glass composition of the present invention can prevent excessive nutrient supply in the aquatic ecosystem due to the controlled elution rate and minimize negative impacts on the environment.

[0029] Furthermore, unlike chemical fertilizers, the glass composition of the present invention optimizes the glass structure to allow useful components to be released slowly, thereby reducing environmental burden and enabling long-term nutrient supply. Through this, the present invention can contribute to minimizing pollution of soil and aquatic ecosystems and preserving biodiversity.

[0030] Furthermore, the present invention allows for the modification of the type and structure of necessary inorganic nutrient substances depending on the type of target and environment for which growth is to be promoted. In other words, the glass composition of the present invention enables the customized design of useful components.

[0031] In addition to the effects described above, the specific effects of the present invention are described together with the specific details for implementing the invention below.

[0032]

[0033] Figure 1 is a process flowchart showing a method for manufacturing glass powder according to an embodiment of the present invention.

[0034]

[0035] The aforementioned objectives, features, and advantages are described in detail below with reference to the attached drawings, thereby enabling those skilled in the art to easily implement the technical concept of the present invention. In describing the present invention, detailed descriptions of known technologies related to the present invention are omitted if it is determined that such descriptions would unnecessarily obscure the essence of the invention. Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings. In the drawings, the same reference numerals are used to indicate the same or similar components.

[0036] Singular expressions used in this specification include plural expressions unless the context clearly indicates otherwise. In this application, terms such as "composed of" or "comprising" should not be interpreted as necessarily including all of the various components or steps described in the specification, and should be interpreted as meaning that some of the components or steps may be omitted or additional components or steps may be included.

[0037] Hereinafter, a glass composition and a method for manufacturing the glass powder according to some embodiments of the present invention will be described.

[0038]

[0039] The glass composition according to the present invention can supply useful components that can help the growth of vegetation and organisms on land and in the ocean.

[0040] For example, the glass composition of the present invention can promote plant root development and growth by supplying nutrients to the soil. In particular, the glass composition of the present invention can continuously supply useful components to plants, thereby increasing crop productivity.

[0041] Furthermore, the glass composition of the present invention can supply nutrients necessary for the growth of algae, microalgae, plants, and other organisms inhabiting aquatic environments. The glass composition of the present invention can promote the proliferation of algae and enhance the growth of seaweed and marine organisms, thereby contributing to the restoration of marine ecosystems and aquaculture.

[0042] In addition, the glass composition of the present invention can prevent excessive nutrient supply in soil or aquatic ecosystems due to the controlled leaching rate and minimize negative environmental impacts.

[0043] The present invention provides a glass composition capable of continuously supplying useful components over a long period of time.

[0044]

[0045] A glass composition according to an embodiment of the present invention comprises P2O530 to 75 wt%; one or more of Na2O and K2O at 10 to 45 wt%; one or more of Al2O3 and SiO2 at 0.1 to 10 wt%; and one or more of MgO and CaO at 0.1 to 15 wt%.

[0046] In addition, the glass composition of the present invention may further include one or more selected from Fe2O3, MnO2, CuO, ZnO, MoO3, TiO2, and Co3O4 in an amount greater than 0 and less than or equal to 15 weight percent.

[0047] In addition, the glass composition of the present invention may further include B2O3 in an amount greater than 0 and less than or equal to 5 weight percent.

[0048]

[0049] Below, the role and content of each component of the glass composition according to the embodiment of the present invention will be explained in detail.

[0050]

[0051] P2O5 is a component that promotes plant root growth while simultaneously facilitating photosynthesis in algae and plants. Furthermore, P2O5 is a substance that forms a glass structure, possesses low chemical durability, and has a P=O double bond. Consequently, P2O5 is polar and highly hydrophilic, allowing it to dissolve easily in water. In the glass composition of the present invention, the release rate of beneficial components is controlled by adjusting the proportion of P2O5 and the content ratios of other components determined therefrom. This allows for a positive influence on the growth of vegetation and organisms.

[0052] The glass composition of the present invention contains 30 to 75 weight% of P2O5. If the content of P2O5 is less than 30 weight%, vitrification of the glass composition may become difficult. Additionally, if the content of P2O5 exceeds 75 weight%, the durability of the glass may rapidly decrease, and a large amount of useful components may be leached out. Accordingly, if P2O5 is added in excess, the persistence of leaching of useful components may decrease.

[0053]

[0054] K2O is a component that plays an essential role in the growth of vegetation and organisms, promoting plant photosynthesis and increasing disease resistance. Furthermore, K2O can regulate intracellular ion balance and growth rates in seaweed cells. Since K2O does not bind with oxygen within glass structures and exists in ionic form, it lowers glass viscosity and controls the dissolution rate. In particular, K2O is a highly useful component for plants and seaweed.

[0055] Na2O plays a role in regulating the osmotic pressure of vegetation and organisms. It is a component that lowers the viscosity of glass and controls the dissolution rate because it exists in ionic form without cross-linking with oxygen within the glass structure. The higher the content of Na2O, the more easily the glass structure can break. Accordingly, Na2O facilitates the dissolution of glass in water, thereby promoting the leaching of useful components.

[0056] The glass composition of the present invention contains one or more of Na2O and K2O in a combined amount of 10 to 45 weight%. If one or more of Na2O and K2O are added in a combined amount of less than 10 weight%, the melting temperature of the glass may increase and the elution rate of useful components may decrease. Conversely, if one or more of Na2O and K2O are added in a large amount exceeding 45 weight% in combined amount, the composition ratio may deviate from the vitrification range and the persistence of elution of useful components may decrease.

[0057] Here, Na2O can be added in an amount greater than 0 to 5 weight% or less, and K2O is more preferably added in an amount of 10 to 40 weight%.

[0058]

[0059] SiO2 is a component that can strengthen plant cell walls, thereby increasing resistance to pests and diseases, and enhance tolerance to environmental stresses such as drought. Additionally, SiO2 is essential for the formation of cell walls in diatoms and contributes to the formation of exoskeletons in some marine organisms. Furthermore, SiO2 is a component that forms structures within glass, increasing its strength and chemical durability, and is a factor that influences the leaching rate. Consequently, if a large amount of SiO2 is added to glass, the glass structure may be strengthened, which could prevent the leaching of useful components.

[0060] Al2O3 is a component that forms the framework of glass and affects its leaching characteristics. If a large amount of Al2O3 is added to the glass composition, the melting temperature of the glass increases, which may make manufacturing difficult. Furthermore, if the Al2O3 content is low, the leaching rate increases, which can lead to the rapid loss of useful components.

[0061] The glass composition of the present invention contains 0.1 to 10 weight% of one or more of Al2O3 and SiO2 in total. If one or more of Al2O3 and SiO2 is less than 0.1 weight%, the durability of the glass may be reduced and it may also be difficult to control the leaching rate. On the other hand, if one or more of Al2O3 and SiO2 exceeds 10 weight%, the leaching rate of the glass may decrease rapidly.

[0062] Preferably, the Al2O3 can be added in an amount of 0.1 to 5 weight%, and the SiO2 can be added in an amount greater than 0 and less than or equal to 5 weight%.

[0063]

[0064] MgO is a component that plays an essential role in the photosynthesis of vegetation and also regulates the dissolution rate of glass. Since the leaching rate can increase rapidly if a large amount of MgO is included in the glass, an appropriate amount must be used after considering the glass design system.

[0065] CaO plays a role in strengthening the cell walls of organisms, thereby increasing their resistance to environmental stress. Additionally, CaO regulates the dissolution rate of glass. Since the dissolution rate can increase rapidly if a large amount of CaO is included in the glass, an appropriate amount must be used after considering the glass design system.

[0066] The aforementioned alkaline earth oxides, such as CaO and MgO, are essentially oxides that act as modifying oxides capable of non-crosslinking within the glass. While vitrification is impossible on their own, it becomes possible when mixed in specific proportions with network-forming agents such as SiO2 and B2O3. Furthermore, the electric field strength generated by the cations of alkali metals is relatively lower compared to that of alkaline earth metals.

[0067] These alkaline earth oxides, such as CaO and MgO, play a role in facilitating easy dissolution in water because their bonds within glass are not strong, and they also act as nutrients for living organisms.

[0068] The glass composition of the present invention contains 0.1 to 15 weight% of one or more of CaO and MgO in total. If the total of one or more of CaO and MgO is less than 0.1 weight%, it may be difficult to deliver useful components to plant and algae ecosystems. On the other hand, if the total of one or more of CaO and MgO exceeds 15 weight%, the composition ratio of the glass may deviate from the vitrification range, and the leaching rate of useful components may increase, which may reduce the persistence of leaching.

[0069] Preferably, the MgO can be added in an amount of 0.1 to 7.5 weight%, and the CaO can be added in an amount of 0.1 to 7.5 weight%.

[0070]

[0071] B2O3 is known as a component that acts as a glass-forming agent to enable sufficient vitrification, similar to SiO2. However, in the present invention, it can be used as a component that plays a useful role for vegetation and organisms.

[0072] The glass composition of the present invention may contain B2O3 in an amount greater than 0 and less than or equal to 5 weight percent. If the content of B2O3 exceeds 5 weight percent, the beneficial components may be supplied in excess to plant and algae ecosystems, which may have a negative effect.

[0073]

[0074] Next, oxides containing useful components refer to components that aid in the growth of vegetation and organisms when glass dissolves in soil or seawater. These components include one or more selected from Fe2O3, MnO2, CuO, ZnO, MoO3, TiO2, and Co3O4.

[0075] The glass composition of the present invention may contain one or more selected from Fe2O3, MnO2, CuO, ZnO, MoO3, TiO2, and Co3O4 in an amount greater than 0 and less than or equal to 15 weight%. More preferably, the glass composition of the present invention may contain 0.1 to 10 weight% of one or more selected from Fe2O3, MnO2, CuO, ZnO, MoO3, TiO2, and Co3O4.

[0076] If the above components exceed 15% by weight, the beneficial components may be oversupplied to the plant and seaweed ecosystems, which could have a negative impact.

[0077]

[0078] In addition, it is preferable that the weight ratio of the content of P2O5 and the content of K2O in the glass composition of the present invention satisfies the following relationship.

[0079]

[0080] [Relationship]

[0081] P2O5 content (weight%) / K2O content (weight%) > 1

[0082]

[0083] If the K2O content exceeds the P2O5 content, the composition ratio of the glass may deviate from the vitrification range.

[0084]

[0085] A method for manufacturing glass powder according to an embodiment of the present invention will be described below with reference to the attached drawings.

[0086] Figure 1 is a process flowchart showing a method for manufacturing glass powder according to an embodiment of the present invention.

[0087] As illustrated in FIG. 1, a method for manufacturing glass powder according to an embodiment of the present invention includes a mixing step (S110), a melting step (S120), a cooling step (S130), and a grinding step (S140).

[0088]

[0089] mix

[0090] In the mixing step (S110), P2O530 to 75 wt%; at least one of Na2O and K2O 10 to 45 wt%; at least one of Al2O3 and SiO2 0.1 to 10 wt%; and at least one of MgO and CaO 0.1 to 15 wt% are mixed and stirred to form a glass composition.

[0091] Here, the glass composition of the present invention may further include one or more selected from Fe2O3, MnO2, CuO, ZnO, MoO3, TiO2 and Co3O4 in an amount greater than 0 and less than or equal to 15 weight%.

[0092] In addition, the glass composition of the present invention may further include B2O3 in an amount greater than 0 and less than or equal to 5 weight percent.

[0093] Here, the Na2O can be added in an amount greater than 0 and less than or equal to 5 weight%, and the K2O can be added in an amount of 10 to 40 weight%.

[0094] In addition, the above Al2O3 may be added in an amount of 0.1 to 5 weight%, and the above SiO2 may be added in an amount greater than 0 and less than or equal to 5 weight%.

[0095] In addition, the MgO can be added in an amount of 0.1 to 7.5 weight%, and the CaO can be added in an amount of 0.1 to 7.5 weight%.

[0096] More preferably, one or more selected from Fe2O3, MnO2, CuO, ZnO, MoO3, TiO2, and Co3O4 may be included in an amount of 0.1 to 10 weight%.

[0097] In addition, the weight ratio of the content of P2O5 and the content of K2O can satisfy the following relationship.

[0098] [Relationship]

[0099] P2O5 content (weight%) / K2O content (weight%) > 1

[0100]

[0101] melting

[0102] In the melting step (S120), the glass composition described above is melted.

[0103] In this step, it is preferable to perform melting at 800 to 1,300°C for 30 to 90 minutes. If the melting temperature is below 800°C or the melting time is less than 30 minutes, the glass composition is not completely melted, which causes a problem of miscibility in the melted glass. Conversely, if the melting temperature exceeds 1,300°C or the melting time exceeds 90 minutes, it is not economical because excessive energy and time are required.

[0104]

[0105] cooling

[0106] In the cooling step (S130), the molten glass composition is cooled.

[0107] At this stage, the cooling method is not particularly limited. For example, it is preferable to perform cooling in a furnace. Since applying air or water cooling can cause severe internal stress in the glass and potentially lead to cracking, furnace cooling is preferred.

[0108]

[0109] smash

[0110] In the grinding step (S140), the cooled glass is ground to obtain glass powder.

[0111] At this time, the grinding method may be any one selected from the commonly known ball mill, jet mill, and planetary mill.

[0112] By this grinding, the glass is finely ground to produce glass powder. It is preferable that this glass powder have an average diameter of 100 µm or less, and a more preferable range may be an average diameter of 30 to 60 µm. Alternatively, it may be controlled to a size of 1 mm or more as needed.

[0113] Glass powder according to an embodiment of the present invention can be manufactured by the above process (S110 ~ S140).

[0114]

[0115] The glass powder produced by the method according to the aforementioned embodiment of the present invention may have useful components added to it that can aid in the growth of terrestrial or marine vegetation and organisms, and is implemented as a water-soluble glass that dissolves well in water, thereby enabling the appropriate supply of nutrients to marine algae, etc.

[0116] As a result, the beneficial components released from the glass powder produced by the method according to the embodiment of the present invention act as a source of nutrients in the soil, promoting the development and growth of plant roots. In particular, the present invention can continuously supply beneficial components to plants, thereby increasing crop productivity.

[0117] Furthermore, the glass powder of the present invention can supply nutrients necessary for the growth of algae, microalgae, plants, and other organisms inhabiting aquatic environments. The glass powder of the present invention can promote the proliferation of algae and enhance the growth of seaweed and marine organisms. Accordingly, the present invention can contribute to the restoration of marine ecosystems and aquaculture.

[0118] In addition, the glass powder of the present invention can prevent excessive nutrient supply in the aquatic ecosystem due to the controlled elution rate and minimize negative environmental impacts.

[0119] Furthermore, unlike chemical fertilizers, the glass powder of the present invention optimizes the glass structure to allow useful components to be released slowly, thereby reducing the environmental burden and enabling long-term nutrient supply. Through this, the present invention can contribute to minimizing pollution of soil and aquatic ecosystems and preserving biodiversity.

[0120] Furthermore, the present invention allows for the modification of the type and structure of necessary inorganic nutrient substances depending on the type of target and environment intended to promote growth. In other words, the glass powder of the present invention enables the customized design of useful components.

[0121]

[0123] Hereinafter, the structure and operation of the present invention will be explained in more detail through preferred embodiments of the present invention. However, these are presented as preferred examples of the present invention and should not be interpreted in any way as limiting the present invention.

[0124] Details not listed here can be sufficiently technically inferred by a person skilled in this field, so their explanation will be omitted.

[0125]

[0126] 1. Preparation of glass powder samples

[0127] Table 1 shows the composition and compositional ratios of glass compositions according to the examples and comparative examples. Reagents were mixed in the weight ratios shown in Table 1 and melted at 800 to 1300°C for 1 hour, after which the molten material was cooled according to the intended use to obtain glass powder. To verify the elution characteristics and growth effects, the powder size was controlled through a grinding process to have a size of 100 µm or less or 1 mm or more. The raw materials used are in the form of oxides, and forms with attached hydrates are also acceptable.

[0128] In addition, vitrification was classified based on cases where a homogeneous glassy appearance is observed, and phenomena involving milky whitening and unmelted material.

[0133] 2. Evaluation of Dissolution Performance

[0134] Distilled water and artificial seawater were used as solvents to analyze the elution performance of the samples. Salt from Marine Art Hi was used for the artificial seawater, and 36.4 g of artificial sea salt was mixed with 1 L of distilled water. For the analysis of elution performance, the samples were immersed in the solvent and left at 25°C for 24 hours. The mass of solute relative to the solvent was set to 1 wt%. After removing the solvent, the samples were homogenized by stirring; the samples were then collected, filtered through a 450 nm filter, and analyzed by ICP-OES measurement. The analysis results are listed in Tables 2 and 3.

[0139]

[0140] Looking at Tables 2 and 3 above, it can be seen that all embodiments of the present invention are vitrified and that a large amount of useful components are leached out. In comparison, it is confirmed that comparative examples, which differ from the composition of the present invention, are unable to vitrify or that useful components are not properly leached out.

[0141]

[0142] 3. Verification test of plant growth effects

[0143] To evaluate the plant growth effect, the growth rate and survival rate of reeds were evaluated using the examples.

[0144]

[0145] The test conditions are listed in Table 4.
