The Characteristics Of Tungsten Crucible
Sep 22, 2017

Tungsten crucible is a core container which widely used in industrial furnace, like sapphire single crystal growth furnace, quartz glass melting furnace, special ceramic sintering furnace and so on. And its working temperature generally reach at 2000 ℃ -2700 ℃. With the character of high purity, high density, no internal cracks, the smooth inside and outside wall , low carbon, low oxygen, low iron and low other impurity, tungsten crucible plays key parts in the process of Sapphire crystal growth.

According to the thermodynamic properties of R & D materials of sapphire growth’s temperature control curve, we developed an unique ratio of raw materials for tungsten crucible, which is much better than ordinary crucible because of its high temperature creep yield strength under high temperature conditions and the high temperature resistance.  We control the existence of oxygen, carbon, iron and other impurity elements strictly to ensure the production of high purity environment.

We produced the tungsten crucible with a uniform grain structure, high density, no defects, precise size to offer custom a longer using life and reduce cost directly. So please contact us without any hesitate if you are interested.
