焙烧高岭土的相变研究

Phase Transition Research of Roast Kaolin with Different Temperature

对湿化学方法处理过的高岭土作不同温度焙烧得不同样品。对不同样品进行ＸＲＤ研究表明，高岭土随焙烧温度的不同发生一系列相变。用ＤＴＡ，ＴＧ，ＩＲ对其相变进行了印证，得到了一致的结果。

We used different temperature to roast the kaolin which have been treated with wet chemistry to get different specimens. The XRD of different specimens showed that there were a series of phase transitions with the different roast temperature of kaolin. We also used DTA、TG、IR confirmed the phase transition, and the result was consistent the XRD.
