Introduction

Tungsten crucible is made of tungsten powder with purity of 99.95% by the method of powder metallurgy and shaped by sintering, stamping or swaging. Meanwhile, it can also be produced by machining from tungsten rod. The crucible made of tungsten is with properties of high temperature resistance, high heat conductivity and low thermal expansion, so that it can be widely used in rare earth smelting, vacuum coating, sapphire growth, etc.
