Why is tungsten material used in quartz glass melting furnaces?

Tungsten materials are widely used due to their special properties, with a melting point of up to 3410 ℃, good wear resistance, high thermal conductivity, low coefficient of thermal expansion, and corrosion resistance.

Tungsten crucibles are mainly used in the following fields:

Tungsten crucibles can be used for quartz glass melting: Tungsten crucibles are also widely used in quartz glass melting furnaces, as one of the important equipment for melting quartz glass. Tungsten can withstand harsh environments such as high temperature and corrosion, ensuring the smooth progress of the smelting process. The high-temperature strength and corrosion resistance of tungsten enable quartz glass to melt and form the desired shape in high-temperature environments.

Tungsten crucibles can also be used for electronic spraying:

In the electronic spraying industry, tungsten crucibles also play an important role. Tungsten can serve as the core component of spraying equipment, withstanding high temperatures and corrosion of spraying materials, ensuring the stability and quality of the spraying process.

Tungsten crucibles can be used for crystal growth:

Eespecially in sapphire single crystal growth furnaces, tungsten crucibles play a crucial role. The tungsten crucible, which has the characteristics of high purity, high density, no internal cracks, precise size, and smooth inner and outer walls, plays a decisive role in the success rate of crystal seeding, quality control of crystal pulling, delamination and sticking pot, and service life during the growth process of sapphire crystals.
