Detail:

Molybdenum Crucibles.High melting point, good high temperature strength of molybdenum, low pollution and good machining performance, which density is relatively low, the tungsten such as light weight, volume and the metal price is cheap, widely used in sapphire crystal, rare earth smelting industry, coating, etc, used for smelting of container.

Molybdenum crucible according to the different production process, can be divided into molybdenum crucible sintering molybdenum crucible and spinning of two kinds.
Spinning molybdenum crucible is a kind of with a piece of molybdenum plate through the integral forming of thin wall crucible spinning process. This process can realize large size thin-walled crucible. Spinning is one of axisymmetrical parts has been used for forming thin-walled pressure processing forming method, it is borrow clubs such as wheel or industrial feed movement, along the same axis rotation in the core mould, metal blank, make its produce continuous local plastic deformation and the hollow.
Spinning molybdenum crucible has good resistance of high temperature creep , plus molybdenum metal originally has a high melting point, good high temperature strength, low pollution, antifriction, corrosion resistance, thermal conductivity, thermal expansion coefficient, good hardenability characteristics, are widely used in sapphire crystal, rare earth smelting industry, coating, etc, as the melting of the container.
