Sintered bodies based on aluminium titanate, process for their production and use thereof.
The present invention relates to sintered bodies based on doped aluminium titanate and mullite as the main phases, having a composition of 50 - 61.5 % by weight of Al2O3, 36 - 47.5 % by weight of titanium oxide, calculated as TiO2, and 2.5 - 5 % by weight of SiO2, the total of the three components adding up to 100 % and including up to 1 % by weight of impurities, and to processes for their production and to the use thereof.
