Molybdenum crucible is made of Mo-1 molybdenum powder, and its operating temperature is 1100℃~1700℃. Mainly used in metallurgical industry, rare earth industry, monocrystalline silicon, solar energy, artificial crystal and machining industries.

Physical and chemical properties

1. Purity: Mo≥99.95%;

2. Density: ≥9.8g/cm3;

3. The highest application temperature environment: 1800°C.

Classification:

Types of molybdenum crucibles: machined crucibles, sintered crucibles, spinning crucibles, stamping crucibles, welding crucibles, etc.

Spinning molybdenum crucible

Spinning is a pressure forming method used to form thin-walled hollow rotary parts. It uses industrial feed motions such as spinning wheels or rods to pressurize the metal blank that rotates along the same axis with the mandrel. It undergoes continuous local plastic deformation to become the desired hollow. The spinning molybdenum crucible is a kind of thin-walled crucible that is integrally formed by a molybdenum plate through the spinning process. This process can realize the production of large-scale thin-walled crucibles.

Sintered molybdenum crucible

Production Process: Molybdenum powder--Sieving--Combination--Isostatic pressing--Rough billet processing--Intermediate frequency sintering--Exquisite car processing--Packaging

Usage:

Because the melting point of molybdenum is as high as 2610°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. The working temperature environment is generally above 2000°C. Especially for sapphire single crystal growth furnaces, molybdenum crucibles with high purity, high density, no internal cracks, precise dimensions, smooth inner and outer walls, etc. have a great impact on the seed crystal success rate, crystal pulling quality control, Decrystallization sticky pan and service life play a key role.
