Tungsten Crucible Applications
Tungsten crucible is widely used to the sapphire growth furnaces, quartz glass melting furnace, crystal furnace, induction furnace, sintering metal mold of high melting point, electronic beam coating, and rare earth smelting furnace. AEM supplies all kinds of Tungsten crucibles and other Tungsten parts (including heaters, heat insulation screens, sheets and supports, etc.) used in the process of sapphire growth and rare-earth melting and we can manufacture the products according to customers’ drawings and specific requirements.
Advantages of Tungsten Crucible from AEM
Our tungsten crucible has advantages of high purity, high density, low resistivity, high strength, low thermal expansion, erosion resistance. In addition, the surface of our tungsten crucible is polished. Therefore, there is no crack and the inside and outside wall is smooth.
