摘要: Mullite whiskers were facilely prepared by sintering kyanite at high temperature, with the addition of AlF3·3H2O. The as-prepared have been characterized systematically in terms phase composition, morphology, and structure. Results showed that morphology size mullite strongly depended on content AlF3·3H2O temperature. At temperatures range 1 100 to 500°C 4 wt% AlF3·3H2O, well-shaped obtained. For an instance, 5–10 μm length 0.1–0.2 cross-section could be formed 400°C, Moreover, results into ceramic matrix enhanced its fracture toughness significantly.
