Ⅳ,Application

Since the melting point of tungsten has reached 3410℃, tungsten crucible (W crucible; wolfram crucible; wolfram barrel; W barrel; wolfram tube, W tube; W pipe; wolfram pipe; wolfram sleeve; tungsten sleeve; wolfram flange; tungsten flange; W flange; wolfram funnel; tungsten funnel) 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.
