The results show that the addition of some rare-earth oxide can greatly reduce the thermal expansion coefficient of Al2TiO5. For example, the addition of 1~4mol% CeO2 or 2mol% La2O3 makes its expansion coefficient come near zero. That gives a new approach in the development of ...

These quantities, inserted in the equations describing the mechanism of the mode excitation and complemented by an independent measurement of the specific heat, allow us to determine the linear expansion coefficient u03b1 of the material. We obtain u03b1 = [(10.9u00b10.4)T+(1.3u00b10.1)T3]...
