  The purpose of this paper is to analyze the effect of molybdenum and cobalt additives on the dielectric, ferroelectric and piezoelectric properties of PZT5piezoceramic material By adding molybdenum and cobalt in the location of zirconate and titanate, in the range of (0-2) percent.For this purpose, the powders were first prepared with a wet chemical method. then They were calcined for 2 hours at 850 ° C. The structural properties of the compounds were investigated using the X-ray diffraction (XRD) method to confirm the formation of single phase compounds (with perovskite structure) at room temperature. The Microstructural analysis of the surface of the sintered discs by scanning electron microscopy (SEM) shows that there is a significant change in grain size with increasing molybdenum and cobalt. Detailed studies of the dielectric properties of PZT In the samples made and tested show measurable change in the piezoelectric charge coefficient D33(Up to 84 ℅ reduction), electromechanical coupling coefficient Keff(Up to 78 ℅ reduction) , resonant frequency Fr(Up to 25 ℅ increase) and mechanical quality factor Qm (Up to 110 ℅ increase).
