A granular fertilizer product having at least two sources of boron having different solubilities to tailor boron availability during the entire growing season of a plant, while reducing the risk of boron toxicity. A first source of boron can include a sodium-based or highly water soluble boron compound such as sodium tetraborate and / or boric acid, while a second source of boron can include a calcium-based boron compound such as colemanite (CaB3O4(OH)3·(H2O)) (e.g. when the carrier fertilizer is N- or K-based) and / or boron phosphate (BPO4) (e.g., when the carrier fertilizer is P-based). The solubility of the first source of boron is higher than the solubility of the second source of boron such that the sources of boron have different release rates into the soil.

The invention relates to a method for producing boron compounds from boron ores such as colemanite and tinkal by means of a photocatalytic process that provides solutions to the high energy requirements, environmental impacts, difficult process conditions, and cost issues arising from conventional chemical processes.

The application discloses a kind of no light kiln glaze and preparation method thereof, belong to kiln glaze technical field, it includes the following mass parts of preparation raw materials: 38~45 parts of sunstone, 20~28 parts of calcite, 10~18 parts of kaolin, 6~14 parts of colemanite, 13~21 parts of strontium carbonate, 1~5 parts of nano zirconium oxide, 5~10 parts of composite colorant, 2~6 parts of microcrystalline control agent, 1~3.5 parts of fluxing regulator.Preparation method includes: S1.wet grinding, aging is obtained glaze pulp after preparation raw materials pretreatment;S2.high pressure glaze is applied to the surface of body and glazing is obtained;S3.glazing body is gradient firing, respectively, low-temperature preheating section, oxidation decomposition section, high-temperature melting section, microcrystalline precipitation section and cooling section.The application solves the technical problems of existing no light kiln glaze glaze surface dry and rough, kiln color single, glaze body matching poor, low yield, so that the glaze surface has kiln texture and high mechanical properties.

The invention relates to the chilled beam system (1) with heat transfer fluid, which quickly cools the indoor air by transferring the heat to the phase-changeable heat transfer fluid in order to bring the air of living spaces to the desired comfort conditions. The invention is especially related to the chilled beam system with a heat transfer fluid containing a heat transfer fluid containing colemanite, borax, Al2O3, SiO3, CuO, TiO2, SiL, szaybelite, boron carbide, boron solid particles between 10-200 nanometers in a heat transfer fluid that can change the phase by taking the ambient air heat passing through the heat exchanger fins and cooling it down.

The application discloses a hard boracite-containing continuous casting protective slag and application thereof, wherein the raw material of the hard boracite-containing continuous casting protective slag comprises hard boracite, and the mass fraction of the hard boracite in the raw material is 1-25%. In the application, the hard boracite is used to replace borax, and the hard boracite can be added in a relatively larger amount in the protective slag, so as to avoid the phenomenon that the addition of too much borax can cause the explosion of the protective slag and the excessive dust to easily cause dust pollution. In addition, the addition of the hard boracite in a large amount can make the content of B2O3 in the protective slag large, the B2O3 can effectively reduce the melting point of the protective slag, refine the protective slag film, reduce the viscosity of the protective slag, and improve the filling flowability and lubricity of the protective slag. Most importantly, the hard boracite can replace part of expensive materials, such as lithium carbonate, under the premise of guaranteeing the performance of the protective slag, so as to reduce the cost of the protective slag.
