Abstract

The crystallization behaviour of YSiAlON glasses with and without ZrO₂ additives, prepared by melting at 1700°C, were studied by means of differential scanning calorimetry, scanning microscopy and X-ray powder diffraction analysis. The optimum nucleation temperatures were determined to be Tg + 65°C and Tg + 50°C for the ZrO₂-free and the ZrO₂-containing glass, respectively. The crystallization of the glasses was found to be dominated by the surface mechanism of nucleation and growth. The added zirconia acted as a growth modifier rather than a nucleating agent.
