ABSTRACT:
A process and apparatus for producing a pressed powder body from at least two different kinds of ultrafine particles. Ultrafine particles of at least two different materials are uniformly mixed together and the mixture is sprayed onto an objective surface whereby the spray pressure causes the particles to adhere and form the pressed powder body. The apparatus includes mixing means, means for conveying the mixture of ultrafine particles, and a pressed powder body forming chamber including nozzle means for spraying the mixture of ultrafine particles, an objective surface and means for evacuating the chamber and introducing an inert gas therein.
