【摘要】 研究了不同粒度配比、不同煅烧温度、不同原料配比下红柱石的烧结性能指出：红柱石开始转化和完全转化为莫来石的温度以及膨胀率和莫来石转化量与煅烧温度、粒度和杂质有关。开始转化温度为１２００～１３００℃，１４００℃反应最剧烈且体积膨胀明显，１５００℃反应趋于完全。更多还原

【Abstract】 Abstract The sintering property of andalusite has been studied with different grain size,burning temperature and raw material ratio. The initial and finished temperature for andalusite decomposition,thermal expansion ratio and mullitization relate to the burning temperature,grain size and impurity content. Andalusites begin to transform into mullites between about 1200￣1300℃,and react strongly at 1400℃.At 1500℃the mullization seems complete.更多还原
