Dielectric and piezoelectric properties of SrBi4−xHoxTi4O15 (x=0.00, 0.02, 0.04 and 0.06) ceramics

The dielectric and piezoelectric properties of SrBi4−xHoxTi4O15 (x=0.00, 0.02, 0.04 and 0.06) ceramics were investigated. SrBi4−xHoxTi4O15 (x=0.00, 0.02, 0.04 and 0.06; SBHT-x) ceramics were synthesized by the conventional solid state reaction sintering method. An X-ray diffraction measurement indicated that a single phase layered perovskite was obtained for all compositions. Studies of dielectric properties with temperature at different frequencies and piezoelectric properties have been carried out.
