ABSTRACT:
A microwave susceptor bed useful for sintering ceramics, ceramic composites and metal powders is disclosed. The susceptor bed contains granules of a major amount of a microwave susceptor material, and a minor amount of a refractory parting agent, either dispersed in the susceptor material, or as a coating on the susceptor material. Alumina is the preferred susceptor material. Carbon is the most preferred parting agent. A sintering process using the bed and novel silicon nitride products produced thereby are described.
