Fabrication of a Strontium-Doped Lanthanum Chromite (LSC) Thin Film on SUS430 Substrate


Article Preview

Lanthanum strontium chromite (LSC) thin films were prepared from the solution of La, Sr, Cr nitrates, acetylacetone and 2-methoxyethanol. Dip-coating technique was used to decompose La0.8Sr0.2CrO3, LSC thin films. The obtained precursor solution was sufficiently spinable and dried gel films were crystallized after heat-treating above 500°C for 2 h. The oxidation at 800°C for 40 hr resulted in no Fe3O4 surface-insulating phase, which means that the LSC thin film would be an effective oxidation-protecting layer of SUS430 substrate. The carbon deposited on an uncoated SUS430 substrate was amorphous with spherical morphology. The obtained LSC thin film was found to be very effective on preventing carbon deposition under dry hydrocarbon atmosphere.
