Abstract

Well-crystallized polycrystalline films of tetragonal PbTiO₃ were successfully synthesized on Ti metal substrate using a hydrothermal method at a low temperature 200°C at 18 kgf/cm² in aqueous solutions of Pb(OH)₂ and a mineralizer such as NaOH and KOH, but PbTiO₃ did not form using LiOH as the mineralizer. At 0.07M Pb(OH)₂, the grain size became larger and the crystallinity became better with an increase of KOH concentration from 1 to 4M.
