云母类矿物的活化释钾性能

Potassium release performance of activated mica type minerals

通过对３ 个典型二八面体型的云母类矿物， 即白云母、绢云母和伊利石的活化释钾试验， 发现云母类矿物热处理产物酸化后钾能大量释放； 探讨了云母类矿物的活化释钾性能。虽然白云母释钾的活化条件相对较高，但其释钾量明显大于绢云母和伊利石。

Tests on potassium release have been done on three typical mica type minerals, i.e. muscovite, sericite and illite. The data show that potassium can be released at a large amount after being thermally treated and acidified; a technique has been proposed to evaluate the performance of potassium release of mica type minerals. Although the activation requirements of potassium release are stricter for muscovite, it can release much more potassium than sericite and illite.
