MATERIALS SYNTHESIS ON THE BASIS OF ULTRAFINE REFRACTORY COMPOUND POWDERS

This article deals with results of investigations devoted to plasma-ch emical synthesis of refractory compounds and their composites in the f orm of ultrafine powders, as well as their application to obtain vario us materials. It is shown that powders synthesized in plasma frequentl y have specific physical and chemical properties, and that they can be successfully applied to obtain high performance ceramics, refractory ceramics, cutting tools, thermal-conducting ceramics, and various coat ings, as well as in the modification of metal structure and properties .
