Electrochemical Synthesis of LaMnO₃ Coatings on Conducting Substrates

Cathodic reduction of a mixed metal nitrate solution containing La 3+ and Mn 2+ ions leads to the deposition of an X-ray amorphous mixed hydroxide coating, which on heat treatment (950 °C, 2 h) yields an adherent coating of LaMnO 3 . This method can be adapted as a simple alternative to such conventional methods of fabricating ceramic films as laser ablation, rf sputtering, and chemical vapor deposition.
