Calcium modified lead titanate (PT) thick films (thicknesses from 50 to 130 μm) are deposited by screen-printing on alumina substrates. First, the influence of the Ca-doping process and of the grain size distribution on the film quality and the piezoelectric coefficients is studied. The permittivity...
