High-quality spherical refractory metal powder is the key raw material for the production of high-performance refractory metal components through advanced powder metallurgy manufacturing and processing technologies, such as hot isostatic pressing, thermal spraying, injection molding and 3D printing. At present, the preparation technologies of the spherical refractory metal powder mainly include physical chemistry method, plasma spheroidization method, plasma atomization method and plasma rotating electrode process. In this paper, the principles of these four types of powder producing methods and the physicochemical properties of refractory metal powders are reviewed, and the technical characteristics and advantages of these four types of powder producing methods are remarked, the future development strategies of the refractory powder producing technology are also pointed out.
