solid nitrides in silicate melts . The mechanism of nitrogen incorporation is
believed to be condensation reactions of hydroxyl and alkoxy groups with
ammonia to produce - Si - NH2 groups and water ( Brinker , 1982 ) . Further

For example , quenching of CaO - SiO2 or MgO - SiO2 melts at rates common in
ordinary glass preparation gives a crystalline product . Dissolution of 10 – 20 - wt
% SizN4 in either melt , followed by the same quench , produces stable ...
