| 摘 要： | 研究了蓝晶石在不同温度、不同介质条件和不同粒度下率为莫来石和ＳｉＯ２的变化规律，实验结果表明，蓝晶石随着粒度的弯细和分解温度降低，它的分解速度大幅度提高，当介质中出现熔体时能够大幅度地提高蓝晶石的分解速度和降低分解温度。

| Abstract: | The behaviour of kyanite decomposing into mullite and SiO_2 in different temperatures, different medium conditions and different grain sizes was studied. The experiments showed that the decrease of grain sizes can largely decrease the decomposing temperature and increase the decomposing speed. When the kyanite is contacting with a melt which produced in decomposing process, the decomposing temperature can be significantly dicreased and the decomposing speed can be largely increased. |
