With the high melting point of 2610℃, molybdenum crucible is widely used as the core container of single crystal sapphire growth furnace,quartz glass melting furnace and rare earth blast furnace ,all the working temperature is above 2000℃.Especially for sapphire single crystal growth furnace, the high purity, high density, free of internal cracks, precise size, smooth inner and outer walls, and other characteristics of molybdenum crucibles, have an big influence to the seed success rate, pulling quality control,crystal stick pan off and working life for sapphire crystal growing.
Advantages
With good resistance to high temperature oxidation and electrochemical corrosion, and no distortion under high temperature ,molybdenum crucible is among excellent high-temperature auxiliary materials.
