首次通过普通烧结工艺合成了具有空心晶须结构的莫来石陶瓷。本文研究了 Bi2O3 和加工对由机械化学活化的 Al2O3 和 SiO2 混合物制成的莫来石陶瓷的莫来石化行为和形态发展的影响。当Bi2O3含量小于10mol%时,莫来石晶粒呈短棒状,没有形成晶须。随着Bi2O3含量增加到10mol%以上，莫来石的形成温度从1400℃降低到1100℃。经1400℃烧结后，形成发育良好的中空结构莫来石晶须。详细讨论了高含量Bi2O3掺杂莫来石陶瓷中空结构晶须的形成过程和生长机理。
Mullite ceramics with hollow whisker structure have been synthesized firstly through ordinary sintering process. The effects of Bi2O3and processing, on mullitization behavior and morphology development of mullite ceramics, derived from the mechanochemically activated mixture of Al2O3and SiO2, were investigated in this paper. When the content of Bi2O3was less than 10 mol%, the mullite grains show a short rod-like morphology, without the formation of whisker. As the content of Bi2O3was increased to more than 10 mol%, the formation temperature of mullite was decreased from 1400 °C to 1100 °C. After sintering at 1400 °C, well-developed mullite whiskers with hollow structure were formed. The formation process and growth mechanism of hollow structural whiskers in mullite ceramic doped with high content of Bi2O3were discussed in detail.
