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.
