Molybdenum powder description
Molybdenum powder is a fine, grayish-black powder that is composed of tiny particles of molybdenum. It has a high melting point of 2623°C (4753°F) and a density of 10.22 grams per cubic centimeter. Molybdenum powder is known for its excellent mechanical and thermal properties, making it highly desirable in various industries.
Molybdenum powder has high tensile strength, low coefficient of thermal expansion, good thermal conductivity, and high corrosion resistance. It also has high electrical conductivity and is resistant to heat and wear. These properties make molybdenum powder suitable for a wide range of applications, including in the production of alloys, chemicals, catalysts, and as a lubricant.
In addition to its physical properties, molybdenum powder is also known for its chemical stability, allowing it to resist oxidation and scaling at high temperatures. This makes it ideal for use in high-temperature applications, such as in the manufacturing of electrical contacts, heating elements, and electrodes.
Molybdenum powder is commonly produced through a process called reduction, where molybdenum oxide is converted into pure molybdenum metal. The resulting powder is then refined and processed to meet specific industry requirements.
Overall, molybdenum powder is a versatile and valuable material that exhibits excellent mechanical, thermal, and chemical properties. Its wide range of applications makes it an essential component in many industries, including aerospace, automotive, electronics, and energy production.
