as per customer's requirement
The heat-resistant fused quartz crucible for sintering is a high-performance container specially designed for high-temperature sintering process. It uses high-purity fused quartz (SiO ₂) as the main raw material, and has excellent high-temperature resistance, chemical inertia and thermal stability. This crucible is widely used in fields such as semiconductor manufacturing, photovoltaic industry, metallurgy, materials science, and laboratory high-temperature experiments, and can meet the personalized needs of different customers.
Product characteristics
1. High purity materials: The main component SiO ₂ content is not less than 99.99%, and the impurity content (such as K ₂ O, Na ₂ O, Fe ₂ O3) is extremely low, ensuring that the material will not be contaminated at high temperatures.
2. Excellent high temperature resistance: The melting point can reach up to 1670 ° C, and the continuous use temperature can reach 1200 ° C. In short-term applications, it can even withstand higher temperatures.
3. Low thermal expansion coefficient: The thermal expansion coefficient is extremely low, about 0.5 × 10 ⁻⁶ K ⁻⊃1;, which can maintain structural stability and strong thermal shock resistance under rapid temperature changes.
4. Good chemical stability: High chemical inertness, resistant to most acids and bases, will not react with molten metal, glass or other materials, ensuring the purity of the melt.
5. Excellent thermal insulation performance: low thermal conductivity (about 0.6-0.7 W/m ·℃), good insulation, and can effectively reduce energy consumption.
6. High dimensional accuracy: Advanced molding technology is adopted to ensure high dimensional accuracy of the crucible, meeting the requirements of precision processes.

Preparation process
The production process of heat-resistant fused quartz crucible for sintering includes the following key steps:
1. Raw material selection: high-purity fused quartz sand is selected to ensure the purity and performance of the crucible.
2. Molding process: According to customer needs, electric arc melting or gas refining methods are used for molding. The arc melting method is suitable for larger crucibles, which melt quartz sand into shape through arc discharge.
3. Sintering treatment: After high-temperature sintering, the structure density and strength of the crucible are ensured.
4. Post processing: including grinding, chamfering, inspection, cleaning and other processes to ensure that the crucible surface is smooth, flat and defect free.
Application scenarios
1. Semiconductor industry: used for the production of monocrystalline silicon and polycrystalline silicon, especially for drawing monocrystalline silicon ingots in the Czochralski process.
2. Photovoltaic industry: In the production of polysilicon ingots, the fused quartz crucible can withstand high temperature without chemical reaction with silicon to ensure the purity of silicon.
3. Metallurgy and Materials Science: Used for melting and casting precious metals and alloys, as well as synthesizing advanced materials such as optical glass and ceramics.
4. Laboratory high-temperature experiments: Suitable for high-temperature experiments that require high purity and low pollution, such as spectroscopic analysis and photochemical applications.
