Summary

Refractory nitrides, borides and carbides can be introduced as dispersed second phases into major ceramic matrices such as A12O3, Si3N4 and Sialons via in-situ chemical reaction sintering. The inclusion of these second phases may increase hardness and improve fracture toughness of these composites or produce electro-discharge machineable materials. Compared with conventional composites in which the second phases are usually directly added, the composites produced via in-situ chemical reactions result in one or more of the following advantages; low cost, unique microstructures, enhanced sinterability or properties.
