K2O－MgO－SiO2－CaF2微晶玻璃的初晶相是KMg2．5Si4O10F2晶体，新出现的晶相依次是：KMg2．5Si4O10F2、Cao·MgO·2SiO2、K2CaMg5Si8O22F2，最终析出晶相总的化学组成和母相玻璃的成份接近，由透辉石CaO·MgO·2SiO2和碱镁闪石K2CaMg5Si8O22F2组成．
The primary phase of K2O-MgO-SiO2-CaF2 glass-Ceramics is tetrasilicic-mica (K2CaMg5Si8O22F2) , the newly formed crystals in this glass-ceramics are KMg2.5Si8 O10F2 , CaO·MgO·2SiO2 andK2CaMg5Si8O22F2 respectively in sequence. The chemical compositions of the final crystals, whichare composed of diopside and richterite, of this type glass-ceramics are almost the same as thoseof the parent glass.
