Welded molybdenum crucible is a high-temperature resistant container made of high-purity molybdenum powder (such as Mo1, TZM, MoLa, etc.) through welding technology. It is mainly used for processing molten metal, glass and other materials in high-temperature experiments and industrial production.
- Features and advantages
High temperature resistance: The melting point of molybdenum is as high as 2610℃. The welded molybdenum crucible can be used for a long time in a high temperature environment above 1600℃, and is suitable for ultra-high temperature material processing.
Chemical stability: It has excellent corrosion resistance to molten metals (such as titanium, zirconium, etc.) and strong acids and alkalis, and avoids the introduction of impurities.
High strength and creep resistance: The structural strength is enhanced through welding process, which is suitable for high load and long-term high temperature conditions.
Customized production: Crucibles of different shapes (such as flat plates, coils, cones, squares, special-shaped pieces) and sizes can be customized according to needs to meet specific application scenarios.
- Manufacturing process
Raw material selection: Use high-purity molybdenum powder (purity ≥99.95%) to ensure the high temperature performance and chemical stability of the material.
Forming process: Molybdenum plates or molybdenum tubes are connected into crucible structures through welding technology, which can realize the production of large-sized thin-walled crucibles.
Surface treatment: black skin, alkali washing, polishing, grinding and other surface treatment options are available to improve the corrosion resistance and service life of the crucible.
Quality testing: Strictly test tensile strength (> 800MPa), density (≥ 9.8g /cm³) and other indicators to ensure that the product meets high purity and high strength requirements.
- Application fields
Metallurgical industry: used for smelting and casting high melting point metals and alloys, such as titanium, zirconium, tungsten, etc.
Rare earth industry: Extracting and refining rare earth elements to avoid contamination by impurities.
Monocrystalline silicon and solar energy industry: key equipment for preparing polycrystalline silicon ingots and improving the quality of monocrystalline silicon.
Artificial crystal industry: growing and manufacturing various artificial crystals, such as sapphire single crystals.
Machining: used for melting and processing of materials in high temperature experiments.
