Glasses containing up to 3.3 wt% nitrogen were prepared in the system MgO-Al[sub 2]O[sub 3]-SiO[sub 2]-AlN-Si[sub 3]N[sub 4]. Glass transition temperature, density, and elastic properties increased with increasing nitrogen content. Resistance against aqueous alkaline solutions was determined by weight loss measurements, solution and surface analysis. The good durability of both oxide and oxynitride glasses is caused by a protective surface layer. The introduction of nitrogen decreases the alkaline attack. The data suggest that nitrogen is incorporated as Si-N bonds.
