METHOD OF PRODUCING HOT PRESSED COMPONENTS

摘要

To form a die part for use in the production of a hot pressed component, boron nitride powder is mixed with a refractory, non-sinterable powder other than boron nitride, and an organic carrier liquid to produce a slurry. The slurry is then caused to flow into the shape of said one die part, and the organic carrier liquid is removed from the slurry to produce a powder compact, which is compressible during hot pressing, the compact being of the shape of said one die part and of substantially uniform density.
