Summary:PURPOSE:To obtain long life and superior heat resistance by supporting a platinum catalyst on a hardened body which contains limited rutile type titanium dioxide, magnesium silicate, silica, and lime aluminate at a prescribed ratio. CONSTITUTION:A carrier of a hardened body consists of 10-30wt% rutile type titanium oxide with 0.25-0.4mum grain size, 10-30wt% magnesium silicate which has 50-100mum grain size and contains >=45wt% silica and <=30wt% magnesia, 10-30wt% spherical porous silica, and 30-50wt% lime aluminate which contains <=42wt% lime and >=50wt% alumina. On this carrier, a platinum metallic catalyst is supported. The catalyst produced as mentioned above has long life and superior heat resistance.
