| description | There are disclosed a manufacturing process and apparatus for a pressed powder body. At least a manufacturing process for a pressed powder body characterized in that at least two kinds of ultrafine particles are mixed together in a carrier gas, and then the resultant mixture gas is sprayed onto an objective surface, so that there may be formed thereon, by a spraying pressure thereof, a pressed powder body comprising an aggregated solid lump of those ultrafine particles. Said resultant pressed powder body may then be subjected to manufacturing process for a pressed powder body as claimed in claim 1, characterized in that the resultant pressed powder body is, then, subjected to a pressing operation in such a condition as it is left or in an enveloped condition while being not heated or being heated at a comparatively low temperature. The apparatus comprises a mixing chamber (1) for mixing said carrier gas and said ultrafine particles (a, b), a pressed powder body forming chamber (14) receiving this mixture through a spraying nozzle (15) therein spraying said mixture onto an objective surface (17), a tubular guide (20) surrounding said objective surface (17). An enveloping tube (25) may contain therein a pressed powder body (c) formed on said surface (17). |
