Abstract
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.
