Abstract

The grain-boundary microcracking materials in the system A1 $_2$ Ti $O_{5}$ -ZrTi $O_4$ (ZAT) is influenced by the thermal expansion anisotropy. The range of ZAT compositions investigated had showed very low thermal expansions of 0.3~1.3 $\times$ 10 $^{-6}$ K compared to 8.29 $\times$ 10 $^{-6}$ K of pure ZrTi $O_4$ and 0.68 $\times$ 10 $^{-6}$ K of polycrystalline A1 $_2$ Ti $O_{5}$ , respectively, compared with the theoretical thermal expansion coefficient for a single crystal of A1 $_2$ Ti $O_{5}$ , 9.70 $\times$ 10 $^{-6}$ K. The low thermal expansion and microcraking temperature are apparently due to a combination of thermal contraction and expansion caused by the large thermal expansion anisotropy of the crystal axes of the A1 $_2$ Ti $O_{5}$ phase.
