Application of tungsten bars: tungsten bars are mainly used for stirring in the rare earth metal smelting process, and can be used as contact materials and electric light source parts. Glass fibers can be used as refractory materials in formers, and electrode materials in the electric arc melting process.
As important components for rare earth smelting, tungsten crucibles have very important service performance and service life. Compared with other kinds of crucibles, tungsten crucibles feature less pollution on smelting metal, long service life, etc. Therefore, tungsten crucibles can be very commonly used in the rare earth industry, and belong to an important achievement for developing and applying highly-processed products of tungsten.
