Abstract

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 α-Cristobalite and Anorthite above 1350℃. With increasing the heat treatment temperature and time, the mean length and aspect ratio of mullite whiskers was gradually increased.
