7.Tungsten crucible is widely applied in industry furnace such as sapphire rowth furnace, quartz
glass melting furnace,and reare earth smelting furnace.The temperature in working
environment of tungsten crucible is above 2000°C.For sapphire crystal growth furnace,high-purity,
high-density, no internal-crack tungsten crucible with other features of exact measurement and
smooth inner 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.
