Spherical molybdenum powder is a metal powder with significant application value. Due to its unique shape and excellent physical and chemical properties, it is used in aerospace, electronics, metallurgy, etc.
Preparation method of spherical molybdenum powder
At present, there are several main methods for preparing spherical molybdenum powder:
Preparation of Spherical Molybdenum Powder by Melting Method
The preparation of spherical molybdenum powder by melting method involves melting high-purity molybdenum powder at a high temperature and then rapidly cooling it with a high-speed coolant to obtain
spherical molybdenum powder. The advantages of this method are high purity, fine particle size, and narrow distribution of spherical molybdenum powder prepared, while the disadvantages are high equipment cost and low production efficiency.
Preparation of Spherical Molybdenum Powder by Gas Phase Method
The preparation of spherical molybdenum powder by gas-phase method utilizes volatile metal compounds to undergo chemical reactions in a gaseous state, generate metal elements, and rapidly cool and solidify to obtain spherical molybdenum powder. The advantages of this method are high purity, fine particle size, narrow distribution of spherical molybdenum powder, high production efficiency, and increased equipment cost.
Preparation of Spherical Molybdenum Powder by Liquid Phase Method
The preparation of spherical molybdenum powder by liquid-phase method involves controlling the crystallization conditions of a metal salt solution to obtain spherical molybdenum powder. The advantages of this method are low equipment cost and high production efficiency, while the disadvantage is that the purity of the prepared spherical molybdenum powder is intense and requires post-treatment and purification.
Properties of Spherical Molybdenum Powder
physical property
Spherical molybdenum powder has physical properties such as high density, high purity, and good flowability. Its thickness can reach 10.2g/cm3, purity can get over 99.95%, and it has good flowability, which is convenient for quality control in the production process.
chemical property
Spherical molybdenum powder has excellent chemical stability and does not react with substances such as acids and alkalis, so special anti-corrosion treatment is not required during the production process. In addition, spherical molybdenum powder has good oxidation resistance and high-temperature stability, which can maintain its physical and chemical properties at high temperatures for a long time.
Structural properties
Spherical molybdenum powder has excellent structural properties, and its lattice constants and single-crystal orientation are the same or similar to those of bulk materials. Therefore, spherical molybdenum powder has good conductivity, thermal conductivity, and mechanical properties in the application process, which is conducive to improving the overall performance and reliability of the material.
