ABSTRACT:
Exhaust purifying filter material which can carry a larger amount of catalyst and from which the catalyst will not easily drop off even if subjected to vibrations or temperature changes due to repeated heating and cooling at high temperatures. Catalyst is carried on alumina whiskers formed on metal fiber having a composition of Fe--Ni--Cr--Al, Fe--Cr--Al or Ni--Cr--Al or woven or unwoven fabric formed of the metal fiber. The catalyst is firmly carried by the alumina whiskers. The amount of catalyst carried is increased with the increase in surface area.
