Tungsten Crucible High-Temperature Resistance For Single Crystal Of Sapphire
1. Product Details:
Tungsten and molybdenum crucible, tungsten and molybdenum reflective thermal insulation screen, and tungsten heating element are the key components of single crystal growth furnace, which have the characteristics of high temperature resistance, low pollution, high temperature resistance creep resistance and so on, providing a strong guarantee for high quality single crystal of sapphire.
Tungsten melting point, high boiling point, high temperature strength, corrosion resistance, high thermal conductivity, small thermal expansion coefficient, good hardenability, thanks to such excellent properties, tungsten crucible is widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth and other industries.
