    Application Since the melting point of tungsten has reached

    3380℃, tungsten crucible is widely applied in industry furnace

    such as sapphire growth furnace, quartz glass melting furnace, and rare

    earth smelting furnace. The temperature in working environment of

    tungsten crucible is above 2000℃. For sapphire crystal growth

    furnace, high-purity, high- density, no internal-crack tungsten crucible

    with other features of exact measurement and smooth surface has decisive

    influence on success ratio of seed growth, quality control of pulling

    crystal, metamictization pot-committed and service life during sapphire

    growth process, and we are willing to be checked by professional units.
