Abstract
Hot Isostatic Pressing (HIP) of ceramics has been recognized as an ideal process to produce fully dense and highly reliable parts in the course of application to ferrite magnetic recording heads, alumina cutting tool inserts, and automobile engine parts made of silicon nitride. Usually these parts are processed by the so-called capsule-free method in which the processed parts are exposed directly to the pressure medium gas. In this case, some interactions between the processed parts and the gas may occur and this phenomenon has to be carefully considered for some nitrides and oxides. Here, the influence of the surrounding gas is termed as an atmosphere and discussed from the viewpoint of thermo-dynamics. Three practical methods to create the desired atmospheres are explained and some examples in the application are given for silicon nitride, superconductive ceramics, and calcium carbonate.
