IRON BASE ALLOY METAL SEPARATION PLATE HAVING RARE EARTH OXIDE PARTICLES DISPERSED THEREIN

The present invention relates to an iron base alloy metal separation plate having rare earth oxide particles dispersed therein, and a manufacturing method thereof, and more specifically, to a non-coated metal separation plate for a high-temperature electrolysis reaction, which applies a ferritic steel based on a Fe base alloy having a thermal expansion coefficient matched with each cell to satisfy requirements of a metal separation plate as a base material, and adds 0.5 to 10 wt% of La_2O_3, which is a rare earth oxide, to improve oxidation resistance and electrical conductivity, wherein rare earth oxide particles (La_2O_3) are used as nanoparticles, such that oxidation resistance and durability are remarkably excellent, and to a manufacturing method thereof.
