The use characteristics of tungsten crucible on the market
At present, tungsten crucible is widely used in quartz glass melting furnace, rare earth smelting furnace and other industrial furnaces, the working temperature of which is generally above 1900℃.Especially for sapphire single crystal tungsten crucible, it has the characteristics of high purity, high density, no internal crack, accurate size and so on.The tungsten crucible plays a key role in the quality control of seed crystal success rate and crystal drawing during sapphire crystal growth.
Due to the high melting point and boiling point of tungsten, high temperature strength, good friction and corrosion resistance, high thermal conductivity, small thermal expansion coefficient, good hardenability, widely used in rare earth smelting quartz glass, electronic spraying crystal growth and other industries.
Tungsten crucible, tungsten rod is one of the well-known tungsten products, the use of molybdenum rod turning processing and welding forming a variety of pure tungsten plate tungsten sheet and pure tungsten rod through the corresponding process. When in use because the temperature is relatively large, we should strictly follow the instructions for production and use, so that both the processed products and our personal safety are guaranteed.
