Spinning molybdenum crucibles is a pressure processing and forming method used to form thin-walled hollow rotary parts by means of industrial feed movements such as spinning wheels or rods, which are pressed against a metal blank that rotates along the same axis as the core die to produce continuous local plastic deformation and become the desired hollow. The spinning molybdenum crucible is a thin-walled crucible made from a single sheet of molybdenum that is formed in one piece by the spinning process. This process enables the production of large thin-walled crucibles.

Moly crucible Production process:

Molybdenum powder - Sieving - Blanking - Isostatic pressing - Rough turning - Medium frequency sintering - Fine turning - Packaging

Moly crucible Uses:

Due to its high melting point of2610°C, molybdenum crucibles are widely used as core containers in industrial furnaces such as sapphire single crystal growth furnaces, quartz glass melting furnaces and rare earth smelting furnaces, where the working temperature environment is generally above2000°C. Especially for sapphire single crystal growth furnaces, the molybdenum crucible with its high purity, high density, no internal cracks, precise dimensions, smooth inner and outer walls, etc. plays a key role in the success rate of the seed crystal, the quality control of the drawn crystal, the de-crystallisation of the sticking pot and the service life of the sapphire crystal growth process.
