Abstract—PbTi0.99Zr0.01O3, a perovskite (ABO3), has been effectively synthesized using the ceramic synthesis method. To verify the structure of the sample , X-ray diffraction was performed on it. The single phased crystalline tertragonal structure with assigned space group P/4mmm was validated by XRD data analysis.  The determined particle size, using the classical Scherer formula, was around 80 nm. The higher sintering temperature is believed to be the cause of the higher particle size. The optical bandgap of the PbTi0.99Zr0.01O3 perovskite sample has been measured and is predicted to be 3.3 eV. After conducting dielectric experiments, it was discovered that the sample exhibited notable dielectric behavior. It is observed that the loss tangent values are modest and the electric permitivity values are comparatively superior. The electric permitivity values are relatively better and the loss tangent values are witnessed to be small. Furthermore, Electrical impedance and electrical modulus were examined to explore conduction mechanism in the as synthesized sample.
