Molybdenum Crucibles For Thermal Sources
Molybdenum Crucibles For Thermal Sources Description
Material selection and processing
- Powder metallurgy: molybdenum powder pressing → sintering → machining (suitable for medium and large crucibles);
- Forging/rolling: the billet is forged at high temperature to refine the grains and improve the strength and density;
- Welding process: complex structure crucibles are spliced by electron beam welding or argon arc welding, and the air tightness of the weld needs to be tested.
Characteristics
- High melting point, good high temperature strength, and excellent high temperature resistance.
- High thermal conductivity, low expansion coefficient, and adapt to rapid temperature changes.
- Strong chemical stability, outstanding corrosion resistance.
- High material purity, low risk of impurity contamination
- Excellent processing performance, high degree of customization
- Wear resistance, long service life, and more cost-effective than similar crucibles.
Application
Molybdenum Crucibles For Thermal Sources are mainly used in high-temperature processing such as high-temperature smelting, sintering, and purification of various metals and other ceramic materials, which can ensure material performance and dimensional accuracy.
01
Vacuum melting and purification of rare earth elements (such as neodymium, praseodymium, dysprosium, terbium, etc.) for the production of permanent magnets, hydrogen storage alloys, etc.
02
Grow large-sized sapphire single crystals (diameter ≥ 200mm) as LED substrates, optical window materials or semiconductor epitaxial substrates.
03
Vacuum induction melting of nickel-based high-temperature alloys (such as Inconel 718) and titanium alloys (such as Ti-6Al-4V) for aircraft engines.
04
Electron beam bombardment melting of high-purity metals (such as Ta, Nb, Zr), with a purity requirement of more than 99.99%.
05
Melting of high-purity borosilicate glass and microcrystalline glass for lenses, optical fiber preforms, etc.
06
Pressureless sintering or hot pressing sintering of silicon nitride (Si₃N₄) and silicon carbide (SiC) ceramics
