- Sialon ceramics were hot isostatic pressed (HIP) at 1820 K, 2050 K and 2100 K using mixtures of Y2O3/Nd2O3 as sintering aids. The overall sialon compositions were selected to obtain either pure beta sialons or mixed alpha-beta sialons with different alpha/beta ratios. The ratio of the Y2O3/Nd2O3 additions was varied from pure yttria to pure neodymia, and the materials have been characterised with respect to phase content, microstructure, chemical composition, Vickers hardness and fracture toughness. The results are compared with those for the same compositions pressureless sintered.
