摘要：The invention is to provide a process capable of producing aluminiummagnesium titanate having a small coefficient of thermal expansion at a firingtemperature lower than 1500° C. The production process of the invention comprisesmaintaining a pre-mixture containing a titania source powder, an alumina source powder,a magnesia source powder and a silica source powder within a temperature range of from1100° C. to 1350° C. for at least 3 hours, followed by heating up to a temperature notlower than 1400° C. and firing at the temperature. The silica source powder is preferablya powder of alkali feldspar. Aluminium magnesium titanate is prepared according to theproduction process of the invention, and the resulting aluminium magnesium titanate isground to give an aluminium magnesium titanate powder.
