摘要
A silicon nitride-based ceramics (97% of the theoretical density, a bending strength limit of up to 700 MPa) is obtained using a microwave sintering method. The procedure of microwave sintering is 7–9 times shorter than the usual sintering process and requires lower temperatures 100–150°C. The material obtained exhibits a highly disperse microstructure and a high content of α-Si3N4 phase.
