99.95% Pure Forged Molybdenum Crucibles Corrosion Resistant

99.95% Pure Forged Molybdenum Crucibles

Description:

Molybdenum crucibles are mainly used as high-temperature furnace containers and can be used in vacuum, inert or reducing gases below 2100°C.

Specifications:

The melting point of molybdenum crucible is as high as 2610°C, so it is often used as a core container in industrial furnaces such as sapphire single crystal growth furnaces, quartz glass smelting furnaces, and rare earth smelting furnaces. The working temperature environment it uses is generally above 2000°C. At present, the LED industry is developing rapidly, and single crystal sapphire has a larger market, which has also expanded the use of molybdenum crucibles. Molybdenum crucibles with characteristics such as high purity, high density, no internal cracks, precise dimensions, smooth inner and outer walls, can produce high-quality sapphire crystals.

Molybdenum crucible usually uses molybdenum powder as raw material, which is molded by a cold precision press and then sintered. After sintering, circulating water is used to cool down the intermediate frequency sintering furnace for 9-10 hours. The molybdenum rod is then taken out and heated in a muffle furnace. Then take it out, use an air hammer with an impact force of 1000 kg, forge it 30-40 times, then use mechanical processing to carve out the groove, and then fine-turn the outer circle and end face to make the surface roughness of the molybdenum crucible reach Ra1.6 -Ra3.2μm, made into molybdenum crucible.
