Tungsten crucible is made of metal tungsten. Tungsten has the characteristics of high melting point, high strength and hardness, good performance at high temperature, low resistivity, small expansion coefficient, and small electronic work function. As containers used in high temperature , tungsten crucibles are widely used in sapphire crystal growth, rare-earth smelting, and coating industries.
