摘要
本文通过大量实验,表明高岭石矿物中(OH)的脱出是不一致的,即外层(OH)易于在470～520℃脱去,内层(OH)在540℃以后脱去,并伴有中间介稳相形成。
The dehydroxylation process and the structural change of kaolinite have been studied by therm-at analysis, X-ray diffraction, IR spectrography, X-ray fluorescence spectrometric analysis and oth-er methods. The hydroxyl groups of outer layer were found to be easily dehydrated at 470～520℃,with the formation of a meta-stable phace. But the hydroxyl groups of inner layer can be dehydratedabove 540℃.
