- Аннотация: A modified method for preparing barium and lead titanate films is suggested, which combines precipitation from solution and elements of sol-gel processing. The ∼1-µm-thick BaTiO3/Pt and PbTiO3/Pt films deposited on Pt foil are transparent, show good adhesion, and have the 1 : 1 : 3 stoichiometry. The films are finegrained, with a mean grain size of 0.1–0.2 µm. The barium titanate films are characterized byt C = 110-125°C, ε20 = 167-500, tanδ20 = 0.015-0.06, εmax = 1050,P s= 3.2 µC/cm2,E c = 14 kV/cm, ρ = (5-7) × 109 Ω cm, andV br = 80-150 kV/cm. The lead titanate films are characterized byc/a = 1.056, ε20 = 105-110, tanδ20 = 0.11-0.16,P s = 4.1 µC/cm2,E c = 34 kV/cm, ρ = (0.8-3.0) × 109 Ω cm, andV br = 50-100 kV/cm.
