Abstract
Typical sintering conditions and microstructures of a few selected compositions of SiC and Si3N4 are presented for these two important structural ceramics. Some significant changes in microstructure and chemical reactions that occur at high temperatures in different atmospheres during sintering are reviewed. Emphasis is placed on identifying and controlling undesirable chemical reactions that compete with the densification process by coarsening the pore/grain microstructures.
