Screen printed BaTi1-xSnxO3 multilayer materials
BaTi1-xSnxO3 (BTS) piezoceramics with multilayer structure were prepared. The Sn concentration in the layers was changed from x=0.025 to 0.15. Thick films were screen-printed on alumina substrates electroded with Ag/Pd. The BTS piezoceramics were sintered at 850degreesC for 10 minutes. The thickness was 45-150 mum depending on the number of layers. The microstructure of piezoceramic materials and the compatibility of BTS layers with substrates were investigated by SEM and EDX. The dielectric properties were measured and the results reported.
