摘要
A new sol-gel system utilizing dihydroxy alcohols as solvents has been developed for the production of lead titanate films. The thickness of crack-free PbTiO3 layers after a single spin coating and firing is approximately 1 mum for a 5:1 solvent-Pb/Ti ratio. This represents a tenfold thickness increase over most sol-gel routes based on methoxyethanol solvent. Coatings with thickness up to approximately 4 mum may be prepared by repeated coating and low temperature annealing steps prior to firing at 600-700-degrees-C.
