Abstract

Thick films of solid solutions of lead-magnesium-niobium-oxide (PMN) and lead-titanate (PTO) were deposited by aerosol combustion. Films consisted of submicron ceramic particles synthesized by combustion of a metalorganic solution in a methane-oxygen flame. The particulate material was deposited on heated substrates (200°C) and subsequently sintered at elevated temperatures. Results varied with starting chemistry and sintering conditions. As-deposited materials were mixed perovskite-pyrochlore phase. Sintering at low temperatures produced pure perovskite material that was not completely dense. Sintering at high temperatures produced dense ceramics of pyrochlore material. This technique requires further optimization for direct deposition of continuous films, but is immediately suitable for producing fine powders for tape casting of capacitors, etc.
