New results for a hot-pressed silicon carbide, hot-pressed aluminum nitride, hot-pressed magnesium fluoride, sintered lead zirconate titanate, two partially-stabilized zirconias, one borosilicate crown glass, cordierite glass ceramic, silicon oxynitride, and five silicon nitrides are presented. Fractographic analysis by conventional means to measure the precrack was difficult or impossible for several of the toughened ceramics. The microstructural tailoring which promotes improved toughness unfortunately generates rougher, more irregular fracture surfaces which make precrack characterization difficult.
