摘要：
In this study, we attempted to recycle the fly ash as a mullite whisker with addition of Al2O3 to obtain the high yield of mullite whisker. During the reaction process, mullite whisker was formed with the reaction of amorphous alpha-Cristobalite and Anorthite above 1350 degrees C. With increasing the heat treatment temperature and time, the mean length and aspect ratio of mullite whiskers was gradually increased.
