Abstract

Sintered ceramic material which comprises doped aluminum titanate and mullite having the composition: PA1 50-61.5% by weight Al.sub.2 O.sub.3, PA1 36-47.5% by weight titanium oxide, expressed as TiO.sub.2, PA1 2.5-5% by weight SiO.sub.2, with the sum total of the three components adding up to 100%, and which further comprises 0.3 to 1% by weight MgO and up to 1% by weight impurities, useful as, inter alia, filters, catalyst supports and internal combustion engine parts, are prepared by mixing and shaping materials of suitable composition and then sintering the shaped composition at temperatures of 1250.degree. to 1600.degree. C. over a holding time of 0.5 to 100 hours.
