内蒙古乌海地区煤系煅烧高岭土活性的探讨

摘要

内蒙古乌海地区煤系高岭土经1 050℃高温煅烧后,具有一定的活性,在有碱激发剂或加热的水溶液中,会生成胶状沉积物,失去原本良好的分散性.本文探讨了煤系高岭土煅烧前后的微观结构变化和活性的来源,及其在加热和不加热状态下,煤系煅烧高岭土在水、酸、碱溶液中不同的分散性.%Wuhai area of Inner Mongolia coal calcined kaolin after 1 050℃ high temperature calcination,it has a certain of activity,in alkali-activator or heating in aqueous solution,lose originally good decentrality,generate colloidal sediment.This article discusses the coal calcined kaolin of before and after the change of microstructure and source of the pozzolanic activity,under the conditions heating and no heating,coal calcined kaolin in different decentrality in water,acid solution and alkali solution.
