    Tungsten Crucible Applications

    Tungsten crucible is widely used in 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.). These are used in the process of sapphire growth and rare-earth melting, and we manufacture the products according to customers’ drawings and requirements.

    Advantages of Tungsten Crucible from AEM

    Our tungsten crucible has the advantage of high purity, high-density, low resistivity, high strength, low thermal expansion, erosion resistance. Also, the surface of our tungsten crucible is polished. Therefore, there is no crack, and the inside and outside walls are smooth.

    Tungsten Crucible Specifications

    We have the world's largest Tungsten crucible, Tungsten tube manufacturing capability, and a maximum diameter of 800mm. The regular density is between 18.0g/cm3~18.3 g/cm3. In some cases, it can reach above 18.7 g/cm3 by our advanced process.
    We can offer all the Tungsten parts of the whole hot zone used in current sapphire growing methods.
