About the molybdenum crucible:
According to different processing methods, molybdenum crucibles can be mainly divided into sintered molding, press molding, spinning molding, turning forming and welding forming.
It is mainly made from turning forming. Molybdenum crucible for vacuum coating refines from Mo-1 powder. Its appropriate working temperature should be within the range from 1100℃ to 1700℃.The melting point of molybdenum crucible for vacuum coating is as high as 2610℃.
Mechanical and chemical properties:
Molybdenum distinguishes itself with those unique properties: high melting point, high creep resistance and low thermal expansion.
The properties of the pure molybdenum could also be improved by alloying. According to the application environments and the operating temperatures, we offer the best molybdenum alloy for our customers.
Molybdenum has extremely good resistance to corrosion by numerous acids, liquid metals and molten glass, provided oxidizing agents
are not present. Molybdenum is relatively inert in hydrogen, ammonia, and nitrogen up to about 1100°C.
Appilications:
Molybdenum is widely used to produce crucibles and other parts for Sapphire crystal growth and rare-earth melting with its high
temperature resistance, low pollution and other good characteristics.
1.Molybdenum crucibles are mainly used in metallurgy industry, mechanism process industry and rare earth smelting industry;
2.They are more frequently used in crystalloid materials and other burgeoning high-tech industries;
3.The crucibles should be used in vacuum or deoxidize atmosphere and the highest using temperature should be no more than 2000ºC.
