Whisker reinforced composites having improved strength and toughness are prepared by a process including densifiion by essentially pressureless sintering. There is no need to hot press or hot isostatic press to achieve a density of 99+% of theoretical for 10 vol. % whiskers and 93+% for 20 vol. % whiskers. The composites are derived from the desired volume fraction of whiskers, a sintering

Characterizing Strength and Failure of Calcium Silie
In order to reach appropriate surface roughness, the thin slices were ground for 40 min using a 1,200-grit Silicon Carbaide (SiC) pad (Electron Microscopy Sciences, Hatfield, Pennsylvania) and cleaned with acetone to remove residue. The flat polished sample was then mounted on a SEM stub using double-sided conductive carbon tape.
