| Abstract: | Several oxynitride glasses were synthesized with and without the addition of a few weight percent of free silicon. For Mg-Si-0-N and Si-Al-0-N glass compositions, the severe frothing (or "bubbling") which was observed during melting could be eliminated completely by the addition of silicon. In a Y-Si-Al-0-N composition, frothing was not observed, even when no silicon was added. The results are used to explain why A1N is superior to Si3N4 for synthesizing transparent oxynitride glasses. |
