But it also includes two fatal disadvantages : first, at is difficult to be sintered and its density is low, which causes its lower strength ; second, in the temperature range of 1023 - 15 73 k, at can decompose into al2o3 and tio2 easily, which can cause the stress concentrated and raise the heat expansion rate
但是該材料本身存在的兩大致命的缺點，在很大程度上限制了它的廣泛應用： （ 1 ） 、鈦酸鋁難以燒結，燒結體的緻密度低，因而強度不高； （ 2 ） 、在750 1300的溫度范圍內易分解成氧化鋁和二氧化鈦，造成材料內部應力集中，並使材料的熱膨脹率升高。 -
For the sake of overcoming the two fatal disadvantages of at that its density and strength is low, and in the middle temperature range it can decompose into ahos and tic > 2 easily. in this dissertation, magnesium dititanate ( mgti2os, m2t ) is introduced to form solid solution to restrain the decomposition and improve the strength of at in high temperature
為克服at強度偏低和中溫域易分解的缺點，本文引入與at晶型相同的二鈦酸鎂（ mgti _ 2o _ 5簡稱m2t ） ，通過與at形成固溶體以抑制鈦酸鋁中溫分解，並滿足其力學強度。
