The Manufacture And Applications Of Tungsten Crucible

What is Wolfram Tiegel?

Wolfram Tiegel is a product manufactured from tungsten. Tungsten crucibles are produced using sinter forming, die casting, spinning and welding methods. Sinter-formed tungsten crucibles are normally applied in sintered powder metallurgy. A small tungsten crucible is produced by turning a tungsten rod. Tungsten crucibles are also produced by processing pure tungsten plate, tungsten sheet and tungsten rod.

What are the applications of Wolfram Tiegel?

Owing to its high melting point, high-temperature strength, significant thermal conductivity and good hardenability, tungsten crucibles can be used under vacuum and inert gases at temperatures up to 2600°C. They are employed in industry for rare earth metallurgy, quartz glass production, MOCVD equipment and electronic injection processes. Tungsten crucibles are also utilised in sapphire crystal growth furnaces, given that their high temperature resistance and low contamination support controlled processing. The tungsten crucible exhibits a purity of ≥99.95%, a density of ≥18.5 g/cm³, precise dimensions and no internal microcracks, thereby improving the yield of sapphire crystal growth.
