Abstract：Spherical titanium powder has the characteristics of high sphericity， good fluidity， high loose density and low oxygen content. The basic principle and current research status of several common preparation processes of spherical titanium powder were introduced， including atomization method， plasma rotation electrode process， plasma torch atomization method and radio frequency plasma spheroidization method. The atomization method is the main production method of spherical titanium powder， including inert gas atomization and centrifugal atomization method. The inert gas atomization method has the characteristics of high production efficiency， wide particle size distribution and high recovery rate of fine powder， which is the main method of producing spherical titanium powder at present. The powder produced by plasma rotary electrode has the characteristics of high sphericity and good fluidity， but low recovery of fine powder. The plasma torch atomizing method can produce titanium powder with high sphericity and good fluidity， but the production cost is higher. The titanium powder produced by radio frequency plasma spheroidization method has the characteristics of high sphericity and good fluidity， but the method has low production capacity. Finally， the powder characteristics of several processes were compared， and the problems in the preparation process of spherical titanium powder were pointed out. The preparation and development direction of spherical titanium powder were prospected.
