What Is The Use Of Tungsten Crucible?

Here are the key applications:
Semiconductor Manufacturing. Tungsten crucibles are ideal for crystal growth processes, where they safely melt and contain high-purity materials for semiconductor production.
Metallurgy.
Chemical Processing.
Glass Manufacturing.
Thin Film Deposition (PVD & CVD)
Laboratory & Research.

Why Tungsten Crucibles are the Best Choice for E-Beam ...
Graphite crucibles also have a higher vapor pressure than tungsten crucibles, which can result in contamination of the vaporized material. Tungsten crucibles are a better choice for e-beam evaporation than graphite crucibles due to their higher melting point, lower vapor pressure, and resistance to chemical attack.

Tungsten is rather resistant to attack by acids, except for mixtures of concentrated nitric and hydrofluoric acids, and it can be attacked rapidly by alkaline oxidizing melts, such as fused mixtures of potassium nitrate and sodium hydroxide or sodium peroxide; aqueous alkalies, however, are without effect.

Crucible Selection Guide
tungsten Crucibles: Highlighted for their high thermal conductivity and excellent thermal shock resistance.
high purity tungsten Crucibles: They are the best crucibles for melting metal and induction heating because of their high-temperature resistance.
