Tungsten Crucible - Tungsten Bar Molding

Tungsten crucible is tungsten product, which is made by many different ways, such as, by pressing molding, welding molding, sintering molding, spinning molding, tungsten bar molding, etc. or using pure tungsten plate, tungsten sheet and pure tungsten bar to processing through the appropriate process. Among them, tungsten bar molding method is unusually used. Such tungsten crucible mold is crescent-shaped, usually 1/4 of the arc, the pressing out curved tungsten, after sintering, its surfaces is presenting metal silver when it is taken out of the sintering furnace, which can be used directly. Then accumulating and folding the sintering tungsten crucible, and then welding the middle crack. Tungsten crucible made by this way, whose structure is more scattered, and the surface is not flat, but after polishing, it may be rounded.

Tungsten crucible features:
Wear resistance;
High temperature resistance;
Corrosion resistance;
Low expansion characteristics at high temperatures;
Purity: W≥99.95%;
Density: ≥18.2g / cm3;
Application temperatures range: 2000-2400 ℃.

Tungsten crucible applications:
Because tungsten crucible melting point is up to 3410 ℃, and its excellent and various performance, tungsten crucible is widely used as a core container for quartz glass melting furnace, sapphire growth furnace, rare earth smelting furnace and other industrial furnace, it can also be used for electronic spraying.
