Aluminum titanate (ATI ~ Al2TiO5) is the stoichiometric mixed phase of alumina and titanium dioxide. Components made of this material can easily withstand abrupt temperature changes of several hundred degrees. Aluminum titanate is sintered at 1,600° C and develops from the oxides Al2O3 und TiO2.
- Low thermal conductivity
- Low wettability by molten aluminum and non-ferrous metals
- Very low coefficient of thermal expansion resulting in very high thermal shock resistance
- Not a dense material, shows certain porosity
Typical application Examples
- Foundry technology, especially in aluminum refineries
- Suitable for applications exposed to very strong thermal cycles
