The paper presents the results of a study of the physico-chemical characteristics of powders obtained in thermal plasma during the treatment of a granular powder of two compositions: 1 - granules consisting of ultrafine titanium particles; 2 - granules of the composition of ultrafine titanium particles and 20 wt. % ultrafine of titanium nitride. The phase and granulometric composition is determined, the internal structure of the processed powder particles is studied.
