“…Silicon carbide whiskers show excellent oxidation resistance in air up to at least 1000 C. The thermal stability of Silar SC-9 whiskers under oxidizing conditions has been studied [57]. Minimal oxidation occurred for whiskers heat treated for 5 h below 1000 C. Heat treatment at 1000 C for up to 96 h resulted in partial oxidation and formation of amorphous silica.…”

Mullite‐SiC‐whisker composites were prepared by powder processing using two commercial SiC whiskers. These composites were prepared by sintering rather than hot‐pressing. A mulliteSlC‐powder composite and a base line mallite material were also prepared for comparison with the two whisker composite materials. Fracture toughness measurements showed significant enhancement in only one of the whisker composite materials. The microstructure of the four materials was examined by scanning electron microscopy and transmission electron microscopy to assist in the explanation of the mechanical behavior of these composites. The examinations suggested that most of the toughening results from second‐phase particles, with only limited toughening from effects associated with whiskers per se. In one case, higher toughness was partially associated with the formation of sialon phase by reaction with the whiskers and the furnace environment.
