ARTIFICIAL CRYSTALLIZATION OF VOLCANIC GLASS TO SODIUM AND POTASSIUM FORM OF CHABAZITE AT ROOM PRESSURE
1969
In this study we used volcanic glass from Kagoshima. In the system of glass+NaOH, initial crystallization of the sodium form of chabazite occurs, followed by a gradual conversion to zeolite X, and finally Na-P zeolite begins to crystallize. In the system of glass+KOH, the potassium form of chabazite was formed after boiling for 14 hours. High structure form of albite was formed from the _??_odium form of chabazite upon heating at 530°C and the potassium form of chabazite was borken upon heating at 1000°C. There is replacement of the type Ca_??_Na2_??_K2 in chabazitc.
