Abstract
A process and apparatus for heating bodies to high temperatures at high pressures. The process involves locating the body in a chamber capable of acting as a resonant cavity for microwave radiation of a predetermined frequency. The body is then irradiated in the cavity with microwave energy of the predetermined frequency for a time sufficient to raise the temperature of the body to a suitable high temperature. Then, either subsequently or simultaneously, a fluid at high pressure is introduced into the cavity to pressurize the body. The apparatus provides the equipment necessary for the operation of the process. The process and apparatus can be used for sintering and/or hot isostatic pressing of bodies made of ceramic powders and for similar purposes.
