A brief summary of recent analytical solutions which accurately describe the experimentally observed toughening behavior in a variety of whisker reinforced ceramics is presented. These results are found to provide important insights into the whisker, matrix, and interface properties required to obta
fl-SiC and a-Si3N 4 whiskers were obtained from bean-curd refuse, the Si source material, at 1200-1400 ยฐC. The addition of CCI accelerated the growth of the SiC whiskers significantly; a whisker length of 1-4 mm and a thickness of 0.2-5 #m (av. 1 /~m) were obtained at 1300 ยฐC after 2 h. Many SiC whi
