Applications and Thermal Durability of Aluminium Titanate Ceramics Having High Thermal Shork Resistance

Aluminium titanate (Al$_2$TiO$_{5}$) as structural ceramics is known as a low thermal exansion, a low thermal conductivity, a low Young's modulus, and excellent thermal shock resistant material. These properities allow for the testing as an insulating material in engines for portliner, piston bottom an turbo charger. However, those composites has low mechanical strength due to the presence of microcracks developed by the large difference in thermal expansion coefficients along crystallographic directions exceed the internal strength of material and its tendency to decompose into $Al_2$O$_3$ and TiO$_2$ at temperature below 130$0^{\circ}C$ limit however the application of aluminium titanate.e.
