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℃.
The melting point of the vacuum coating crucible is 2610oC and the density is higher than the sintered crucibles. Molybdenum crucibles are widely used in sapphire single crystal growth and the industry of silex glass, melting furnace and rare-earth smelting.
Sintered tungsten crucible is applied to many fields because its melting metals and metal oxide have certain corrosion resistant properties. It can be applied to fused corundum crystal growth techniques. Sintered tungsten crucible also can be used as hot evaporation and hot deposition’s container for various material in electrons.
molybdenum crucibles are mainly used in metallurgy industry, mechanism process industry and rare earth smelting industry; are more frequently used in crystalloid materials and other burgeoning high-tech industries; crucibles should be used in vacuum or deoxidize atmosphere and the highest using temperature should be no more than 2000oC.
