Semiconductor Crystal Growth Applications: Used in the LEC (Liquid Encapsulated Czochralski) process for the growth of compound semiconductor single crystals such as GaAs and InP, serving as a crucible for holding molten materials.

High-Purity Environment Applications: Its high purity and non-reactivity with molten materials effectively prevent contamination, ensuring high crystal quality.

High-Temperature Reaction Crucibles: Suitable for high-temperature chemical reactions and melting experiments of metals or compounds, offering excellent corrosion resistance and thermal shock resistance.

Vacuum and Inert Atmosphere Applications: Stable for long-term operation in vacuum or inert gases such as nitrogen and argon, without decomposition or volatilization.

Crystal Growth Equipment Integration: Commonly used in combination with tungsten, molybdenum, and graphite heating systems in LEC crystal growth furnaces, MOCVD equipment, and other high-temperature melting systems.
