Abstract： Significance of particle spheroidization and research statuses in domestic and overseas were summarily introduced， which makes particles with irregular shape into spherical using a certain method. Physical and chemical methods for preparing spherical particles were illustrated. Taking titanium particles， silicon particles and tungsten particles as examples， excellent performances of the spherical particles and their application in industry were expatiated. The results show that the spheroidized particles have better performances and wider application areas.
