This note is an overview of current developments in the field of refractory materials using plasma processes. In this sector, which often necessitates high temperatures, it is surprising to note that few plasma processes have been developed for industrial production purposes. Three aspects or three types of application are discussed: -melting or remelting of oxidized refractory materials (electromelted materials) -synthesis of refractory powders, notably oxides, carbides or nitrides -spheroidizing of refractory oxide powders.
