Silicon nitride structural ceramics with an elevated strength at 1300°C

A high-temperature ceramics based on Si3N4 with an ultimate bending strength of 620 MPa at room temperature and 450 MPa at 1300°C has been developed using hot pressure casting and compression sintering. The ceramics is characterized by a high degree of crystallization of the intergrain phase and the...
