Crucible and preparation method thereof
The invention provides a crucible and a preparation method thereof, and relates to the technical field of crucibles. The preparation method of the crucible comprises the following steps: preparing a gel premixed solution; adding silicon nitride powder, a sintering aid and a dispersing agent into the gel premixed liquid to obtain gel slurry; adding an initiator and a catalyst into the gel slurry, uniformly mixing, injecting into a mold, and drying to obtain a biscuit; putting the biscuit into a rubber discharging furnace for rubber discharging treatment; and carrying out pressureless sintering treatment on the biscuit subjected to glue discharging treatment. According to the preparation method of the crucible, pressureless sintering can be adopted, the requirement for equipment is low, and the preparation method is suitable for preparing the silicon nitride crucible for continuous crystal pulling.
本申请提供一种坩埚及其制备方法，涉及坩埚技术领域。该坩埚的制备方法包括：制备凝胶预混液；在凝胶预混液内添加氮化硅粉、烧结助剂和分散剂，以得到凝胶浆料；将引发剂和催化剂添加至凝胶浆料中，并在混合均匀后注入至模具中且进行干燥处理，以得到素坯；将素坯置于排胶炉中进行排胶处理；将经排胶处理后的素坯进行无压烧结处理。该坩埚的制备方法能够采用无压烧结，对设备需求低，适用于制备用于连续拉晶的氮化硅坩埚。
