摘要
设计了一系列对比实验,以三氧化二铝和锐钛矿型二氧化钛为基本原料,研究了复合添加剂氧化铈和氧化镁对钛酸铝合成与稳定的影响,探讨了复合添加剂对钛酸铝的稳定机理,并在合成的基础上,对钛酸铝材料进行了烧结后性能测试,结果表明,复合添加剂能使钛酸铝材料保持较好的综合性能,氧化镁比氧化铈对钛酸铝的合成及稳定具有更好的作用,烧结后钛酸铝材料保持低热膨胀系数。
A series of comparison experiments were first designed and then aluminum titanate specimens were synthesized using aluminum oxide and anatase titanium as basic raw materials. Effects of composite cerium oxide and magnesium oxide additives on their synthesis and stability, and the mechanism of their stabilization by these additives were explored. Tests of these modified aluminum titanate materials after sintering show： the composite additives help maintain their good performance, magnesium oxide works better than cerium oxide in their synthesis and stabilization, and their thermal expansion coefficients are low.
