Abstract:
1. An aluminum magnesium titanate honeycomb carrier for an exhaust gas-cleaning catalyst, wherein the material for the aluminum magnesium titanate honeycomb carrier is an aluminum magnesium titanate sintered product obtained by firing at from 1,000 to 1,700° C. a raw mixture comprising: 100 parts by mass, as calculated as oxides, of a mixture comprising a Mg-containing compound, an Al-containing compound and a Ti-containing compound in the same metal component ratio as the metal component ratio of Mg, Al and Ti in an aluminum magnesium titanate represented by the empirical formula Mg from 1 to 10 parts by mass of an alkali feldspar represented by the empirical formula (Na a remaining ratio α (%) of the aluminum magnesium titanate honeycomb carrier is higher than the remaining ratio α (%) of an aluminum titanate honeycomb carrier after both the aluminum magnesium titanate honeycomb carrier and the aluminum titanate honeycomb carrier are held at 1100° C. for 300 hrs, wherein the aluminum titanate honeycomb carrier is obtained by firing at 1400° C. a mixture of α-alumina and anatase-type titanium oxide and an alkali feldspar represented by (Na solid-solubilized Si
