Abstract
High dense Si3N4 ceramic bodies with additives of nitrides such as A1N, TiN, YN, VN, NbN and ZrN were fabricated by high pressure hot-pressing and HIPing under the conditions of 0.15–3.0 GPa and 1650°C–1800°C for 1 hour. Temperature dependences of Vickers microhardness (Hv) and fracture toughness (KIC) were measured from room temperature to 1200°C. Only little change in Hv and KIC was observed in this temperature range.
