Powder metallurgy is a technological process for obtaining metal powders or using metal powders (or mixtures of metal powders and non-metal powders) as raw materials to produce metal materials, composite materials, and various types of products through forming and sintering.

The production process can be divided into five stages: powder preparation, mixing, molding, sintering, and post-treatment. Powder metallurgy has similarities with ceramic production in terms of powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials.

Powder metallurgy technology has many advantages, such as flexible processes, precise forming, high utilization rate, and the ability to prepare multiphase materials and nanomaterials. This makes powder metallurgy play a pivotal role in the development of new materials and become the key to solving new material issues. Powder metallurgy has a wide range of applications, including automobiles, digital electronics, household appliances, hardware tools, communications, and medical devices.

In summary, powder metallurgy is an important material preparation technology with broad application prospects and tremendous development potential.
