Preparation and Characterization of Al₂TiO₅- Si₃N₄ Composites by Reaction Sintering Process

Abstract:

Al₂TiO₅-Si₃N₄ composites were prepared by reaction sintering process using Al₂TiO₅ and α-Si₃N₄ powders as raw materials. The effect ofsintering temperature, soaking time and Si₃N₄ content on the sintering properties of the composites was studied. The results showed that the best sintering temperature and soaking time were 1550 °C and 2 h, respectively. The samples with 15 wt% of Si₃N₄ addition had good sintering properties, and its mechanical strength was 28.96 MPa, which was 2 times of the one of the samples without Si₃N₄ addition.
