High Purity 99.95% Molybdenum Crucibles
1. High Purity 99.95% Molybdenum Crucibles
Molybdenum has strong corrosion resistance. Apart from tantalum and tungsten, molybdenum is known to have the highest melting point of the pure elements. Molybdenum crucibles are widely used in heat exchanger method (HEM) processes. They are suitable for melting and solidifying single crystals. The high purity 99.95% molybdenum crucibles has thin walls and excellent creep resistance.
2. High purity 99.95% molybdenum crucible is a kind of container mainly used in the metallurgical industry, rare earth industry, monocrystalline silicon, solar energy, artificial crystal, and machining industries. High purity 99.95% molybdenum crucible manufacturing process is introduced below, and its specific steps are as follows:
1) Using molybdenum powder as a raw material;
2) Formed by cold and other precision press;
3) Sintering treatment;
4) After sintering, use circulating water to cool down the intermediate frequency sintering furnace for 9-10 hours;
5) Take out the molybdenum rod and heat it in the muffle furnace;
6) Take out the molybdenum rod, use an air hammer with an impact force of 1000 kg, and forge it 30-40 times;
7) The groove, the outer circle, and the end face are made by machining so that the surface roughness of the molybdenum crucible reaches Ra1.6-Ra3.2μm, and the high purity 99.95% molybdenum crucibles is made.
The high purity 99.95% molybdenum crucibles are manufactured by this process has the advantages of reducing cost and requiring less equipment. It is first made into a solid powdery cylindrical billet and then undergoes secondary high-temperature crystallization to refine the grains, the strength and high-temperature resistance of the crucible are improved.
