3,Application
Since the melting point of tungsten has reached 3410°C, 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°C. 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.
Tungsten crucible Liners are very useful in electron-beam evaporation as they typically increase the evaporation rates of the material being deposited and they simplify the task of changing from one evaporation material to another. Crucible Liners are available in a variety of sizes.
