ELECTROLYTIC PZT FILMS

A novel method of cathodic deposition of complex oxide compounds has b een demonstrated on the deposition of ferroelectric PZT films. In the proposed approach, PZT film formation on graphite and carbon fibre mat substrates was achieved via a peroxoprecursor. It was established tha t the atomic ratio of lead, zirconium and titanium in the deposit clos ely corresponded to that in the starting solutions. Formation of a per ovskite PZT phase was observed at 500 degrees C. By variation of curre nt density and deposition time the amount of the deposited material co uld be controlled. It was established that films obtained from solutio ns with hydrogen peroxide as an additive showed less tendency to crack .
