Abstract: 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.
