Description

Technical Field

[0001] This utility model belongs to the field of yttrium metal processing technology, specifically relating to a crucible for yttrium metal sintering. Background Technology

[0002] In the continuous development of modern materials science and industrial production, yttrium, due to its unique physicochemical properties, has demonstrated extremely important application value in many high-end fields. From advanced electronic information industries to cutting-edge aerospace technology, and to the development of new energy sources that are crucial to people's livelihoods, various materials and components manufactured with yttrium are continuously driving technological innovation and product upgrades in these industries.

[0003] Application CN202222019233.9 discloses a crucible for sintering large-size substrates. The side plates are connected to the connecting plates via slots that engage with mounting slots in the connecting plates. This ensures that the thickness at the connection point is the same as the rest of the crucible, avoiding unnecessary economic losses during substrate sintering. Furthermore, it ensures a relatively uniform stress distribution across the silicon nitride crucible assembly, preventing damage caused by significant regional differences in stress distribution. To ensure the service life of the silicon nitride crucible, which consists of a boron nitride crucible base plate, side plates, connecting plates, and a boron nitride crucible top cover, the two side plates and two connecting plates are fitted onto the outside of multiple mounting plates through multiple square grooves. The bottom of the multiple mounting plates is fixedly connected to the movable plate. Therefore, the movable plate set inside the groove limits the side plates and connecting plates, ensuring the stability of the installation of the boron nitride crucible base plate, side plates, and boron nitride crucible top cover, and improving the working stability of the silicon nitride crucible composed of the boron nitride crucible base plate, side plates, connecting plates, and boron nitride crucible top cover.

[0004] However, the crucibles proposed in the aforementioned document require different supports for each size. If the support is not stable enough, the crucible may tilt, affecting the production of yttrium and resulting in inconsistent product quality, making it difficult to meet the high-quality and high-stability requirements of high-end yttrium products.

[0026] Example

[0027] Reference Figure 1-4 This embodiment of the present invention provides a crucible for sintering yttrium metal, comprising:

[0028] The support structure 100 includes a base 101, a bracket 102 fixedly connected to the upper end of the base 101, a connector 103 slidably installed on the side wall of the bracket 102, and a support 104 installed at the end of the connector 103.

[0029] The crucible structure 200 includes a shell 201 inserted into the side wall of the support member 104, a heat-insulating coating 202 pasted on the inner wall of the shell 201, a ceramic layer 203 disposed inside the heat-insulating coating 202, and a release coating 204 coated on the inner wall of the ceramic layer 203. The support member 104 is symmetrically installed on the side wall of the shell 201, and the lower end of the shell 201 extends to the middle of the support 102.

[0030] The base 101 serves as the foundation of the entire support structure, ensuring that the entire equipment remains stable during yttrium sintering without displacement due to external forces or vibrations. The bracket 102 is fixedly connected to the upper end of the base 101, supporting the weight of the crucible structure 200 and the internal yttrium raw material during sintering. The sidewalls of the bracket 102 are equipped with specific slides or grooves for the sliding installation of the connector 103. By sliding along the sidewalls of the bracket 102, the connector 103 can adjust the position of the support member 104 to accommodate crucible structures 200 of different sizes. The end of the support member 104 is in close contact with the sidewall of the outer shell 201, providing stable support for the crucible structure 200. The outer shell 201, as the outermost layer of the crucible structure, is typically made of high-strength metal materials such as stainless steel. An insulating coating 202 is adhered to the inner wall of the outer shell 201 and is made of materials with good thermal insulation properties, such as ceramic fiber coating. Its function is to reduce heat loss from the inside of the crucible to the outside during the sintering of yttrium metal, maintaining a high-temperature environment inside the crucible, which helps improve sintering efficiency and quality. The ceramic layer 203 is located inside the insulating coating 202. The ceramic layer 203 is made of a special ceramic material that is resistant to high temperatures and corrosion, such as yttrium oxide-stabilized zirconia ceramic. This ceramic material has a high melting point and good chemical stability, effectively resisting the erosion of the crucible's inner wall by the complex physicochemical reactions that occur during the high-temperature sintering of yttrium metal, thus extending the crucible's service life. The release coating 204 is applied to the inner wall of the ceramic layer 203. The release coating 204 is made of a material with an extremely low coefficient of surface friction, such as a polytetrafluoroethylene (PTFE) coating. Its function is to reduce the adhesion between the finished yttrium metal and the inner wall of the crucible after sintering, allowing the finished yttrium metal to be easily removed from the crucible.

[0031] Specifically, the crucible structure 200 also includes a limiting block 205 fixedly connected to the outer wall of the outer shell 201, with the limiting block 205 located at the end of the support member 104.

[0032] The limiting block 205 is fixedly connected to the outer wall of the outer shell 201. The limiting block 205 is generally a block structure made of metal. Its position corresponds to the end of the support member 104. When the support member 104 is supported on the side wall of the outer shell 201, the limiting block 205 is engaged with the end of the support member 104, further restricting the position of the outer shell 201 on the support member 104 and preventing it from shifting during use.

[0033] Furthermore, the crucible structure 200 also includes a side strip 206 fixedly connected to the upper end of the outer shell 201, and an ear hook 207 fixedly connected to the upper end of the side strip 206, the side wall of the side strip 206 extending to the side wall of the release coating 204.

[0034] The edge strip 206 is fixedly connected to the upper end of the outer shell 201. The edge strip 206 is typically a metal strip, with its sidewalls extending to the sidewalls of the release coating 204. The edge strip 206 increases the strength of the upper end of the outer shell 201 and provides a connection base for the installation of the ear hooks 207. The ear hooks 207 are fixedly connected to the upper end of the edge strip 206 and are generally hook-shaped structures made of metal. Their function is to facilitate operation by the operator using hooks or other tools when the crucible structure 200 needs to be moved or transported, thus improving the ease of handling the crucible structure.

[0035] Furthermore, the support structure 100 also includes a lead screw 105 rotatably mounted on the side wall of the bracket 102, and a handle 106 fixedly connected to the end of the lead screw 105, the end of the lead screw 105 being threadedly connected to the center of the connector 103.

[0036] The lead screw 105 is rotatably mounted on the side wall of the bracket 102. The lead screw 105 is connected to the bracket 102 via bearings and other rotating connecting components, ensuring smooth rotation of the lead screw 105. The end of the lead screw 105 is threadedly connected to the center of the connector 103. When the lead screw 105 is rotated, due to the transmission action of the thread, the connector 103 slides along the axial direction of the lead screw 105 on the side wall of the bracket 102, thereby achieving precise adjustment of the position of the support member 104. The handle 106 is fixedly connected to the end of the lead screw 105. The handle 106 is typically designed in a shape that is easy for the operator to grip and rotate, such as round or T-shaped. By rotating the handle 106, the operator can easily drive the lead screw 105 to rotate, thereby adjusting the position of the support member 104, making the operation simple and convenient.

[0037] Preferably, the support structure 100 also includes a pin 107 inserted into the upper side wall of the connector 103, with the end of the pin 107 inserted into the middle of the through hole in the side wall of the bracket 102.

[0038] The pin 107 is inserted into the upper side wall of the connector 103. One end of the pin 107 has a specific shape for easy insertion and removal by the operator. A series of through holes are provided on the corresponding positions of the side wall of the bracket 102. When the connector 103 is adjusted to the appropriate position, inserting the end of the pin 107 into the through hole on the side wall of the bracket 102 can fix the connector 103 in its current position, preventing it from sliding due to external forces or other factors during use and ensuring the stability of the support structure.

[0039] It should be noted that the support structure 100 also includes a stop 108 inserted into the middle side wall of the bracket 102, with the end of the stop 108 extending to the side wall of the housing 201.

[0040] The stop block 108 is inserted into the middle side wall of the support 102, and the end of the stop block 108 extends to the side wall of the outer shell 201. The stop block 108 is generally a block structure made of metal. Its function is to limit the horizontal displacement of the outer shell 201 after the crucible structure 200 is installed in place, thereby further improving the stability of the crucible during the sintering process.

[0041] Preferably, the support structure 100 further includes a support plate 109 slidably mounted on the inner wall of the bracket 102, and a handle bolt 110 threadedly connected to the side wall of the support plate 109. The end of the support plate 109 extends to the bottom of the housing 201, and the end of the handle bolt 110 passes through the side wall of the support plate 109 and is inserted into the middle of the through hole in the side wall of the bracket 102.

[0042] The support plate 109 is slidably mounted on the inner wall of the bracket 102, and the support plate 109 and the bracket 102 are slidably connected by a structure such as a guide rail or a sliding groove. The end of the support plate 109 extends to the bottom of the outer shell 201, providing additional support for the bottom of the outer shell 201. The handle bolt 110 is threadedly connected to the side wall of the support plate 109, and the end of the handle bolt 110 passes through the side wall of the support plate 109 and is inserted into the middle of the through hole in the side wall of the bracket 102. By rotating the handle bolt 110, the position of the support plate 109 on the inner wall of the bracket 102 can be adjusted. After the support plate 109 is adjusted to the appropriate position, the handle bolt 110 is tightened to fix the support plate 109 in the current position, so as to adapt to the crucible structure 200 of different heights and provide stable support for its bottom heating component.

[0043] In use, firstly, based on the dimensions of the crucible structure 200, the operator rotates the handle 106, causing the lead screw 105 to rotate, allowing the connector 103 to slide on the side wall of the support 102, thereby adjusting the position of the support 104 so that it can accurately support the outer shell 201 at a suitable position on the side wall. After adjusting the position, the pin 107 is inserted into the through hole in the side wall of the support 102 to fix the position of the connector 103. Then, the crucible structure 200 is placed on the support 104, with the lower end of the outer shell 201 extending to the middle of the support 102. At this time, the stop 108 restricts the horizontal displacement of the outer shell 201, and the support plate 109 can be adjusted as needed to provide support for the bottom of the outer shell 201. The position of the support plate 109 is fixed by rotating the handle bolt 110. Throughout the yttrium sintering process, the support structure 100 stably supports the crucible structure 200, ensuring the smooth progress of the sintering process. During the yttrium sintering process, the yttrium raw material is placed into the crucible structure 200. The ceramic layer 203 first withstands the high temperature and the physicochemical reaction of the yttrium, and its high-temperature resistance and corrosion resistance protect the entire crucible structure. The heat-insulating coating 202 retains heat inside the crucible as much as possible, reducing heat loss and maintaining a stable high-temperature sintering environment. After sintering, the release coating 204 minimizes the friction between the finished yttrium product and the inner wall of the crucible, making it easy to remove the finished yttrium product. The limiting block 205 ensures that the outer shell 201 is fixed on the support 104 during use. The side strip 206 and the lugs 207 play a role in handling the crucible structure 200, allowing operators to easily move the crucible using the lugs 207.

[0044] In summary, the position of the support component 104 can be precisely adjusted through the cooperation of the lead screw 105 and the handle 106, adapting to crucible structures 200 of different sizes and improving the versatility of the device. The base 101 provides a stable foundation, the bracket 102 has sufficient strength and rigidity, the stop block 108 restricts horizontal displacement, the support plate 109 and the handle bolt 110 provide bottom support, and the pin rod 107 fixes the position of the connecting component 103. These multiple aspects ensure the stability of the support structure 100 during the yttrium sintering process, ensuring that the sintering process is not disturbed. The design of components such as the handle 106 and the pin rod 107 allows operators to easily adjust and fix the position of the support structure, simplifying operation and improving work efficiency. The limit block 205 ensures the stable installation of the crucible on the support structure, and the design of the side strip 206 and the ear hook 207 facilitates the handling of the crucible structure, improving operational convenience.
