Abstract

본 발명은 금속 섬유 소결체 특히, 고온 내구성을 구비한 금속 소결체에 관한 것이고, 이 소결체는 Fe-Cr-Al-REM계 스테인레스강의 박판을 감은 코일재의 단면을 선삭하여 만들어진 섬유를 원료로 하고, 이 Fe-Cr-Al-REM계 스테인레스강 섬유를 소정 두께로 집적하고, 소결되어 있다.
본 발명에 의한 금속 섬유 소결체는 500∼1,000℃의 고온에서 양호하고 안정된 기계적 성질을 구비하며, 그 자체의 뛰어난 통전성에 의하여 고온 유지를 위한 특별한 열원을 필요로 하지 않고, 직접 통전만으로 그 자체의 발열에 의하여 고온 유지를 할 수 있다.
