The description and main features of ceramic crucibles
1. Material: 99% alumina, corundum-mullite ceramic, zirconium oxide ceramics, boron nitride optional
2. Shape: we supply various shapes, including cylinder, rectangular, square, boat, and so on. 
3. Features: all-ceramic crucibles are with excellent chemical resistance, thermal - shock performance. 
4. Working temperature: It can be work under max. 1650ºC long term in air, or higher temperature under inert gas
5. Application: They are commonly used in a variety of metal or non-metal melting material, or melting items analysis in the lab, also it's a regular application for smelting & sintering for phosphors, rare earth material, precious metals.
