Since the silicon carbide sinters at a much higher temperature (versus the zinc oxide), it remains inert and inhibits densifiion. Inert particles reduce the volume of the sintering phase and exert a restraint on shrinkage [66 68]. This restraint causes tensile stresses in the matrix which can possibly induce cracking.
