Qingdao Baidun Ceramic Technology Co., LTD
1. Raw Material Preparation: High-purity silicon carbide powder is prepared. The purity and granularity of the powder are crucial for the final properties of the crucible.
2. Mixing and Forming: The silicon carbide powder is mixed with a binder to form a homogeneous mixture. This mixture is then formed into the shape of a crucible using various forming techniques such as dry pressing, isostatic pressing, or slip casting.
3. Inspection and Finishing: After sintering, the crucibles are inspected for defects and finished by grinding or machining to achieve the required dimensions and surface finish.
4. Drying Kilm: In some processes, a curing step may be included to cross-link the binder and improve the structural integrity of the green body before sintering.
5. Crucible coating is an important process used to improve the performance of crucible in high temperature environments, for melting materials such as high purity silicon.
6. Gas Kiln:The crucible is placed in the gas kiln for the final stage of firing.

Isostatic Pressing Machine
Isostatic press is a molding equipment that works under ultra-high pressure. It uses oil, water or gas as the working medium, and uses the same ultra-high pressure force in all directions for all surfaces of the object, so that the density of the formed workpiece is high and uniform, and the sintering contraction is uniform and easy to process.
The production of silicon carbide crucibles is a meticulous process that requires precise control over materials, forming, and firing to achieve the high-performance characteristics these crucibles are known for. The final product is a crucible capable of withstanding extreme temperatures and providing excellent corrosion resistance and thermal shock resistance, making them suitable for a variety of high-temperature applications.
