Abstract Different ways to control the properties of the piezoceramic material based on solid solution system of zirconate-titanate of lead – PZT-19 were explored. Various embodiments of doping to improve the dielectric and piezoelectric properties while maintaining the operating temperature and as a dopant selected barium cations. Measured and calculated all electrical, piezoelectric and elastic characteristics. The data obtained allow a computer simulation of piezoelectric elements of any shape and size, made of modified material for subsequent application in instrument. Conducted research on the stability of the resulting material under cyclic exposure to elevated temperatures. The graphs of the relative permittivity and the piezoelectric coefficient d33 of the maximum temperature reached during cycling. A comparative analysis of the properties obtained on a modified material with the requirements of the industry standard for PZT-19. The new material has improved properties in comparison with PZT-19, and the stability in the temperature range up to 200 °C.
