Summary

Si-Y-Al-O-N glasses containing up to 15 at.% N were formed by melting mixtures of Si3N4 and constituent oxides at 1600°–1800°C. The glasses had microhardnesses as high as 1058 kg/mm2 (Knoop, 100-g load) and elastic moduli as high as 186 GPa. Full recrystallization required temperatures of 1400°–1450°C, and crystalline phases present after heat treatment included Si3N4, Y-Si and Y-Al oxides, and Y-Si oxynitrides.
