Influence of Composition on the Characterization and Crystallization of Calcium-Magnesium-Silicate Glass-Ceramics
The effects of replacement of MgO by CaO,on the characterization and crystallization behavior of glas-ceramics in the CaO-MgO-SiO2 system were investigated by DTA,XRD and FTIR techniques and by density measurements.The results show that the glass transition temperature (Tg) and crystallization temperature (Tc) increase and glassy structural network becomes denser with increasing the CaO/MgO weight ratio.After certain heat-treatment procedure,the major crystal phases change from calcium magnesium silicate (diopside) to calcium silicate (parawollastonite) at the replace of MgO by CaO.Studying of density measurement shows that,the density of glass samples increase by increasing CaO content on the expense of MgO.
