Abstract
An apparatus for forming ceramic or metal powders has a plasma generator, a source of material in the form of powder particles and a projection torch for passing the material through the plasma to melt the powder particles and then projecting a stream of plasma and material via an outlet. A container is provided for containing the projected stream. A plurality of spray diffusers are arranged to diffuse a spray of cryogenic liquid into a space through which the projected stream travels, whereby the projected stream is quenched. A console controls the flow rates of the powder particles and the plasma into the projection torch.
