Owing to its excellent dielectric and ferroelectric properties, BaTiO3 is one of the most extensively studied ferroelectric materials and is currently utilized in a wide variety of fields including multilayer capacitors, transducers, actuators, electro-optical devices, electromechanical devices, dynamic random-access memory, field-effect transistors, and thermistors, among others. Taking into the consideration these applications, Hf has been selected as the substituent for BaTiO3 (BaTi0.9Hf0.1O3) to modify its physical properties. Hereby, we report synthesis of BaTi0.9Hf0.1O3 using solid state route and investigated its crystallization via XRD and also emphasized on its dielectric and impedance characteristics. XRD analysis reveals tetragonal crystal structure of the synthesized sample. Dielectric measurements as a function of frequency infer the sample to inherit higher dielectric permittivity with relatively. Conduction mechanism was investigated using electric modulus and impedance studies. Impedance study reveals non-ideal Debye-like behavior of the ceramic.
