Influence of Compositions on Phase Separation in R_2O-CaO-ZnO-Al_2O_3-SiO_2 System
Source abstract
Abstract
The influence of compositions on phase separation in R2O-CaO-ZnO-Al2O3-SiO2system was investigated in detail by OM and TEM. The studied results show that a wide miscibilitygap is in K2O- CaO-ZnO-Al2O3-SiO2 system and it will down to the region of the concentrationsof low Al2O3 and high SiO2 with the equimolecular substitution of K2O by Na2O, and the higherthe content of ZnO is, the larger the phase separation region is. It is evident that in the region oflow Al1O3 concentration the tendency towards phase separation increases with increasing Al2O3content and when Al2O3 content is above 6.20 mol% this tendency decreases with increasing Al2O3content.
