Disclosed is a starting mixture for the preparation of a sintered body on a basis of aluminum titanate consists of more than 46 wt.-% TiO2, up to 49.5 wt.-% Al2O3, 3 to 5 wt.-% quartz, and less than 0.2 wt.-% impurities, Al2O3 and TiO2 being present in the weight ratio of 1:0.95 to 1:1.05. The sintered body according to the invention is composed of: 15 to 35 wt.-% TiO2; 60 to 85 wt.-% Al2TiO5 (aluminum titanate); up to 5 wt.-% Al2O3; up to 17 wt.-% Mullite; and max. 0.2 wt.-% impurities, all parts by weight together totaling 100 wt.-%. Also disclosed are processes for making the sintered body.
