Abstract
The preparation of a glass and its devitrification at 1200°C in the Yb-Si-Al-0-N system with the composition in equivalent % of 35eloYb:45e/oSi:20e/oAl:83eloO:17eIoN is reported. The properties of the glass and the glass-ceramic are examined. Changes observed in density, Young's modulus, hardness and fracture toughness during devitrification are represented. Oxidation studies have been carried out to examine the oxidation resistance of the glass and the glass ceramic under air and under water vapour. For the glass and the glass-ceramic no weight changes were observed up to 900°C. A weight gain of 1% was observed on heating under air during heating to 1200°C for the glass. For the glass-ceramic, no weight changes are observed up to 1200°C.
