Molybdenum Crucible
Molybdenum crucible is a high-temperature resistant container made of molybdenum (Mo) or its alloys, which is mainly used for melting, heat treating and refining various materials at extremely high temperatures in laboratories and industrial applications.
Characteristics and applications of molybdenum crucible:
1. High melting point: Molybdenum has a very high melting point (approximately 2623°C or 4809°F), which allows molybdenum crucibles to remain solid at temperatures where most other metals melt, making them ideal for use in smelting processes at high temperatures.
2. Corrosion resistance: Molybdenum has good corrosion resistance to many chemicals, especially in reducing environments. Therefore, it can be used to handle substances that corrode or react with ordinary crucible materials.
3. Thermal stability: Molybdenum has good thermal stability and can withstand rapid heating and cooling without cracking or deformation.
4. Electrical conductivity: Molybdenum has a certain electrical conductivity, which means that it can be used in equipment such as electric arc furnaces for electrical heating.
5. Application: Molybdenum crucible is usually used in laboratory research, smelting of metals and alloys, crystal growth, ceramic sintering, semiconductor manufacturing and as reaction vessels in some special chemical processes.
6. Production materials: Although pure molybdenum can be used to make crucibles, in order to improve its strength and oxidation resistance, molybdenum alloys are usually used, or a layer of anti-oxidation coating is coated on the molybdenum surface.
7. Precautions: Although molybdenum crucible is useful in many aspects, you need to pay attention when using it because when the temperature exceeds 500°C, it is easily oxidized in the air to form volatile oxides, which may be harmful to the operator's health. Health risks are posed and appropriate ventilation measures are required.
