Preparation Technology and Research Status of Molybdenum Powder

Molybdenum powder is the main raw material for the production of molybdenum and molybdenum alloy. Its quality affects the performance of molybdenum and molybdenum alloys. The paper introduces the traditional preparation technologies of molybdenum powder, such as hydrogen reduction method, plasma reduction method, carbonyl thermal decomposition, sol-gel method. It also introduces preparation of ultrafine molybdenum powder, nanosize molybdenum powder and high purity molybdenum powder. In short, the various needs of different performance and quality molybdenum powder products were made by different preparation methods. Improvement of the purity, yield, production efficiency and reduction of production costs must be the direction of preparation of molybdenum powder.
