Claim 5:
6. A Fe—Al-based metal porous membrane, wherein the Fe—Al-based metal porous membrane comprises a sintered metal substrate layer (1), and a sintered hybrid membrane layer (2) composed of a Fe—Al-based metal powder and a metal fiber powder, wherein, the sintered hybrid membrane layer (2) composed of a Fe—Al-based metal powder and a metal fiber powder is disposed above the sintered metal substrate layer (1); and
wherein, the sintered metal substrate layer (1) and the sintered hybrid membrane layer (2) composed of a Fe—Al-based metal powder and a metal fiber powder are obtained, by casting a water-based solution containing an organic additive, the Fe—Al-based metal powder and the metal fiber powder, through a casting machine, to form a membrane green body on a metal substrate layer (1), and drying, and thereafter removing organic substances and performing high-temperature sintering and predetermined-temperature reaction synthesis;
a Al powder is further added into the Fe—Al-based metal powder.
