At present,tungsten crucible is widely used in quartz glass melting furnace,rare earth smelting furnace and other industrial furnaces,and its working temperature environment is generally above 1900℃.Especially for sapphire single crystal tungsten crucible,it has the characteristics of high purity,high density,no internal crack and precise size.The tungsten crucible plays a key role in the quality control of the seed success rate of sapphire crystal growth and the use of the decrystallization cauldron.
Due to its high melting point and boiling point,high temperature strength,good resistance to friction and corrosion,high thermal conductivity,small thermal expansion coefficient,good hardenability,widely used in rare earth smelting quartz glass,electronic spraying crystal growth and other industries.
