Radiochemical study of hydroxide films. III. Deposition of ferric hydroxide films on glass

Thin ferric hydroxide films with a homogeneous top layer were deposited from solutions on glass substrates. Radiochemical studies showed the manner in which difficulty soluble iron compounds are deposited in thin films and compositional changes in the product formed as a function of growth time. The films and species precipitated in the solutions were found to be ferric hydroxide contaminated with sulfur; and carbon-containing compounds. The composition of the thin films and precipitates varied with deposition time. Film growth, observed to be stepwise, was compared with results of electron microscopy, x-ray diffraction, and derivatographic studies
