Molybdenum crucible is sintered and forged from the final material. Generally speaking, molybdenum crucible is made of pure molybdenum, which can prevent the molten metal powder from mixing. The density of molybdenum crucible is greater than 9.8g/cm3, and its working temperature is between 1100℃. In addition to tungsten crucible in metal smelting industry, it is another good choice.
Molybdenum crucible physical properties: 1. Purity: M≥99.95%; 2. Density: ≥9.8g/cm3; 3. Maximum application temperature environment: 2400℃.
Molybdenum crucible is widely used in metallurgical industry, rare earth industry, artificial crystal and machinery. Since the melting point of molybdenum is as high as 2610℃, molybdenum crucibles are also widely used as core containers in industrial furnaces such as sapphire single crystal growth furnaces, quartz glass melting furnaces, and rare earth smelting furnaces. The working temperature environment of molybdenum crucibles is generally above 2000℃. Especially for sapphire single crystal growth furnaces, molybdenum crucibles with high purity, high density, no internal cracks, precise dimensions, and smooth inner and outer walls play a key role in the success rate of seeding, quality control of crystal pulling, de-crystallization and pot sticking during the growth of sapphire crystals.
