Powder metallurgy is a process technique for producing metal powder or metal powder (or a mixture of metal powder and nonmetal powder) as a raw material, and then forming and sintering the raw material to produce metal materials, composite materials and various products. The powder metallurgy method has similar places to the production of ceramics and belongs to the powder sintering technology, so a series of new powder metallurgy technologies can also be used for preparing ceramic materials. Due to the advantages of the powder metallurgy technology, the powder metallurgy technology becomes a key for solving the problem of new materials, and plays a significant role in the development of the new materials.
