BaTi1-xSnxO3 (BTS) powders, with x ranging from 0 to 0.15, were synthesized by solid-state reaction technique. The powders were pressed and sintered at 1370 degrees C. Obtained BTS ceramics were investigated by X-ray diffraction and dielectric properties measurements. It is found that Curie temperature decreases while dielectric constant increases with increasing of tin content. A monolithic multilayered ceramics with up to five layers of BTS with different amounts of Sn were prepared. Their dielectric properties were examined. Relatively high dielectric constants in a wide temperature range were obtained. It is noticed that BTS mono- and multilayered ceramics have better dielectric properties if they are additionally treated in microwave oven for 10 min, after sintering at 1370 degrees C.
