| 摘 要： | The relationship between kaolinite structure and the temperature of thermal transformation of phase was discussed in this paper through grinding and henting treatment. The results show that the structure of kaolinite is destroyed rapidly with mechanical grinding time, and the kaolinite structure collapses completely after 1 h grinding. The temperature of thermal transfomlation of phase of decreases with the destruction of kaolinite structure. This result has a great significance for the utilization of kaolinitic rocks in China coal measures. |
