Abstract
The possibility of synthesizing powders based on tungsten carbides in atmospheric electrical arc plasma with the use of tungsten oxide as an initial tungsten source is shown. It has been established that the phase composition of the vacuumless arc synthesis product depends on the supplied energy. Tungsten carbide is presented by both particles of nearly several tens of micrometers in size and particles of nanometer range with a maximum of distribution from 5 to 15 nm.
