铵明矾

针对以往采用传统酸熔法和碱熔法从高岭土制备硫酸铝铵（铵明矾）工艺过程存在的诸多缺点，对滇南某高岭土矿样采取微波酸化-中和联合操作路线，制取铵明矾产品。

In order to overcome some disadvantages existing in the traditional acid fusion and alkali fusion method of extraction of ammonium aluminum sulfate from kaolin , the microwave acidification and neutralization are used to extract ammonium aluminum sulfate from a kaolin mineral sample in south of Yunnan province .
