Molybdenum crucible is sintered or forged from the ultimate material—molybdenum powder. Generally speaking, molybdenum crucible is used pure molybdenum, for its purity can prevent melting metal powder from mingling. The density of molybdenum crucible is more than /cm3, and its working temperature is among 1100℃.
Pressed-sintered crucibles. During sapphire production, Al 2 O 3 - the compound that is to become the future single crystal - is melted in molybdenum and tungsten crucibles. It is in the Kyropoulos process that our pressed-sintered crucibles show their strengths to best effect. They are repeatedly heated to more than 2000°C (3632 °F)
