Abstract
A ceramic having improved thermal shock resistance is produced by a method comprising firing a mixture comprising at least one compound selected from the group consisting of a sulfate, nitrate, carbonate, oxide, hydroxide, acetate and oxalate of an alkali metal or an alkaline earth metal, titanium oxide, rehydratable alumina, optionally silica and optionally a rare earth element compound at a temperature in the range of 1,000.degree. C. to 1,300.degree. C.
