摘　　要：采用2种原料分别为高铝矾土和氧化钛、工业氧化铝和氧化钛,粉料经过预烧之后经成形、烧结制备陶瓷。为了比较2种制品,分别对其进行了抗压强度、抗折强度、热膨胀系数、热震稳定性测试及微观形貌观察。结果表明,采用前者为原料制备的陶瓷性能可以与后者相媲美,同时由于高铝矾土价格便宜,因此更适用于工业生产的需要。In the paper we use two raw materials which were high alumina clayand TiO2, Al2O3 and TiO2. Powder of the two formulars above weresintered by presintering and forming. Crushing strength, bending strength, bulk density, thermal shock resistance and heat expansion coefficient ofthe samples prepared were tested. The results show that aluminum titan- ateceramics whose raw materials were TiO2 and high aluminum clay rivalwith tradition method matrials, possess excellent combined properties. Due to the low cost of high alumina clay,it were more suit to the industrymaufacture.
