摘要：
Mullite- corundum insulation material with nano crystals in matrix was fabricated by gel-casting process. The results showed that the volatilization temperature of organisms is 285 degrees C-600 degrees C, there is no glass phase appeared in specimens; The mullitization begin at 1000 degrees C, along with the raise of temperature, the quantity of mullite phase increases, especially during 1200 degrees C- 1400 degrees C; when the temperature is up to 1550 degrees C, mullite becomes the main crystal phase and there are also some corundum crystals in the specimens; The specimen matrix sintered at 1550 degrees C is consisted of nano crystals 80nm in length and 10-20nm in diameter.
