Research on Al₂TiO₅-Si₃N₄ Composites Fabricated by Reaction Method

Abstract:

Al₂TiO₅-Si₃N₄ composites were fabricated by mixing 75-95% premixed powder, composed of titanium dioxide, α-Al₂O₃ powder, and suitable amount of stabilizing agents such as MgO, SiO₂ and ZrO_2, and 5-25% α-Si₃N₄ and being sintering at 1450-1550°C in nitrogen atmosphere. The effects of Si₃N₄ content, sintering temperature and soaking temperature on the properties of Al₂TiO₅-Si₃N₄ composites were investigated. The results showed that the optimum formula for Al₂TiO₅-Si₃N₄ composites was 90% premixed powder and 10% α-Si₃N₄. The optimum technological parameter was that sintering time was 1550°C for 2h.
