Aluminum titanate

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.

Properties

  • 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
