Abstract (en)
[origin: EP0505067A1] A shaped body is formed from fine particles such as powder, whiskers or short fibers of ceramics or metal, by preparing a mold (34) having a mold chamber (42), an inlet port (36) open to the mold chamber at its first portion and adapted to introduce a mixture of the fine particles and a carrier fluid into the mold chamber, and an outlet port (44) open to the mold chamber at its second portion substantially opposite to the first portion and adapted to exhaust substantially only the carrier fluid in a gaseous state out of the mold chamber (42); preparing the mixture of the fine particles and the carrier fluid; and supplying the mixture under a pressure elevated substantially above atmospheric pressure into the mold chamber through the inlet port (36) while exhausting the carrier fluid out of the mold chamber through the outlet port (44). <IMAGE>
