Abstract

A review of some behaviour diagrams in the Y-Si-Al-O-N system indicated that the liquid region, and hence the glass forming region, could be more extensive than previously documented. Apart from the glass-forming region of Drew et al at 1700°C, the solid liquid reactions in the β-SiAlON- Y₃Al₅O₁₂ system, seen as liquid isotherms at 1550°C, 1650°C and 1750°C, are indicated by Tien. The representation of these is shown on the Jänecke prism. Various compositions were fired at 1700°C to determine the extent of the region in which glass formed. The areas of glass formation are indicated for the different M-Si-Al-ON systems investigated, (M= Y, Nd, Sm, Dy, Yb). Mechanical properties have been investigated and compared with lower Al content glass compositions in these system (i.e. 28M:56Si:16Al:83O:17N e/o).
