Molybdenum powder
Molybdenum and molybdenum alloys have the characteristics of high temperature strength and high temperature hardness, good thermal and electrical conductivity, and good corrosion resistance. Therefore, it is widely used in chemical industry, metallurgy and aerospace industry. In recent years, with the rapid development of high-tech, the requirements of high-tech on the properties of molybdenum and alloy materials have exceeded the traditional performance indicators in many aspects. Therefore, the modern preparation technology of molybdenum products is facing both challenges and opportunities. Among them, the preparation of molybdenum powder is the first step in the development of molybdenum industry technology. At present, the preparation of molybdenum powder has been relatively mature, but it still needs further development and improvement, especially for the preparation technology of ultra-fine phase powder for some special purposes and the recovery of molybdenum from molybdenum powder and its preparation waste.
According to the use, there are three kinds of molybdenum powder: molybdenum powder for pressing, spherical molybdenum powder for heating spraying and superfine molybdenum powder for special conditions. In addition, molybdenum alloy molybdenum powder is prepared by adding appropriate amount of Ni, Cr, B, Si and other elements. Therefore, in order to meet the needs of different types of molybdenum powder, it is required to study the technology and process of preparing various molybdenum powder.
