18/08/2007 · A modified sol–gel method has been developed to prepare for the barium strontium titanate (, BST) thick films. The films were deposited on either Pd–Ag electroded alumina substrates (Pd–Ag/Al2O3) or silver electroded alumina (Ag/Al2O3) substrates by spin coating technique or screen technique. The thickness of the film was in the range of 2–10 μm.
