A glass-ceramic in the calcia-yttria-alumina-silica system was prepared through the melt, sinter, sol-gel and solution routes. The development of a calcium yttrium silicate phase was found to depend significantly on the method of processing the glass. This is attributed to the strong influence of the surface/interface on reactivity. X-ray diffraction and Fourier transform infrared techniques were used for identification. The processing methods were also evaluated and compared for product quality and economy in cost.
