Abstract:

A series of glasses whose compositions are expressed by the general formula xCaO.(1-x)SiO₂ with x=0.40, 0.50, 0.60 were prepared. The glass structure and devitrification behaviour were studied by Fourier transform infrared absorption analysis,differential thermal analysis and x-ray diffraction analysis. The crystallising phases were identified and a crystallisation mechanism proposed. The CaO richest term of the series exhibits a drastic change in the glass structure and in crystallising phases.
