Physical And Chemical Properties Of Tungsten Crucible

2024-01-05 18:00:06

Tungsten crucible is one of the metal tungsten products. The product made by powder metallurgy is widely used in rare earth industry, mainly used for smelting and electrolysis to produce rare earth metals and their oxides. The service life of tungsten crucible is longer than that of molybdenum crucible, tantalum crucible and other crucible.

Tungsten Crucibles of Chinese manufacture

Physical and chemical properties of tungsten crucible, its purity: W≥99.95, density: ≥18.5g/cm cubed, the highest application temperature environment is 2400℃, high melting point boiling point, high temperature strength, corrosion resistance, high heat conductivity, small coefficient of thermal expansion, good hardenability. This series of properties makes the finished products more corrosion-resistant. In particular, replacing molybdenum crucible with tungsten crucible can reduce the content of molybdenum and tantalum in rare earth metals. Therefore, tungsten crucible is particularly suitable for the production of high purity rare earth metals, and the demand for it in rare earth industry is also increasing day by day.
