Abstract

1340604 Iron oxide WESTERN ELECTRIC CO Inc 19 April 1971 [17 April 1970] 26732/71 Heading C1A [Also in Division G2] Iron oxide having a botryoidal morphology is vapour deposited on a substrate heated at 100 -160‹ C. from an iron compound (especially iron pentacarbonyl) which has been thermally decomposed in an oxidizing or inert medium.
