Effect of additive content on the microstructure and room‐temperature and high‐temperature mechanical properties of Si <sub>3</sub> N <sub>4</sub> ceramics
Abstract Si 3 N 4 ceramics with uniform grain size distribution were fabricated using spark plasma sintering method and post‐heat treatment. The effect of sintering additive content on the grain growth and room‐temperature and high‐temperature mechanical properties of Si 3 N 4 ceramics were studied. By modulating the competitive growth of β‐Si 3 N 4 grains along the basal and the prism planes, the grains in Si 3 N 4 ceramics were homogeneous. The room‐temperature and high‐temperature flexural strength of the samples after post‐heat treatment were tested. At temperature above 1300°C, the samples with lower sintering additive content exhibit higher strength.
