ABSTRACT:
The present invention provides a car exhaust purifying filter member which is high in the capacity to collect solid and liquid contents in exhausts and which has such high heat resistance as to be capable of withstanding heat when burned for cleaning and a method of manufacturing the same. A three-dimensional mesh-like metallic porous member made from Ni--Cr--Al and having a three-dimensional framework is heated at 800-1000 .degree. C. in the atmosphere to form on its surface a densely grown fibrous alumina crystal. This member is used as a filter member. Such a filter member shows excellent collecting capacity and corrosion resistance and can withstand high temperatures. Also, it is possible to firmly carry a catalyst on the fibrous alumina crystal formed on the surface. Because of its increased surface area, it has an increased catalyst carrying capacity.
