Due to the high melting point of molybdenum reaching 2610 ℃, molybdenum crucibles are widely used as core containers in industrial furnaces such as sapphire single crystal growth furnaces, quartz glass melting furnaces, rare earth smelting furnaces, etc. Their working temperature environment of molybdenum crucibles is generally above 2000 ℃. Especially for sapphire single crystal growth furnaces, molybdenum crucibles with characteristics such as high purity, high density, no internal cracks, precise size, smooth inner and outer walls, etc. play a crucial role in the success rate of seed crystallization, quality control of crystal pulling, crystallization adhesion pot, and service life of sapphire crystal growth process
