Application
Making parts for CVD, ion implants, photolithography, and semiconductor parts.
• Ideal for products such as injector tubes, gas nozzles, and insulators in traditional industries.
• Material for industrial furnaces.
• Protector for high-temperature thermal couples.
• Material for the chemical industry due to its high corrosion resistance.
The both are used as container of materials or products produced or used for analysis and firing in various industries, applicable to coal analysis, metal analysis and smelting, analysis and firing of chemical raw materials, analysis and founding of glass, analysis and firing of raw material and minerals such as rare earth, firing of high temperature products like ceramic, and founding of monocrystal raw materials, etc.
