Al2TiO5 Aluminium titanate overview
Al2TiO5 Aluminium titanate ceramic is the stoichiometric solid solution of Al2O3 aluminium oxide and TiO2 titanium dioxide.
The outstanding thermal shock resistance of aluminium titanate results from the low coefficient of thermal expansion on the macroscopic scale, in combination with the low modulus of elasticity. The dependency of the strength and of the modulus of elasticity on temperature also have what for ceramics are unusual curves. Both values increase as the temperature rises, effects that are again due to the closing of the micro-cracks at higher temperatures.
Al2TiO5 Aluminium titanate characteristics
- Low modulus of elasticity
- Low thermal conductivity
- Very low coefficients of thermal expansion
- Excellent thermal shock resistance
- Low wettability by molten non-ferrous metals
Al2TiO5 Aluminium titanate applications
The material is used, for instance, in portliners, cylinder liners and vehicle engines, in the spacing rings of catalytic converters, as kiln furniture and in foundry engineering. Here it is particularly found in aluminium smelting works where it is used for rising pipes and proportioning pipes, nozzles, crucibles, flow regulators and so forth.
