Abstract

Crystalline metal and ceramic bodies that have previously been sintered to the extent that the only porosity remaining in the body is closed porosity are isostatically hot pressed to a still higher density by surrounding the body which is maintained at sintering temperature with a gas at a pressure of at least 10,000 p.s.i. The gas must be inert to the body being pressed and must not permeate the body during the hot isostatic pressing step. Pref. the material is alumina and the gas is He, the firing being carried out using H2.
