Study of Dielectric and Thermal Properties of Zirconia Nanoparticles

Zirconium dioxide (ZrO2) nanoparticles were synthesized using the thermal decomposition method. Further, the structural, thermal, and dielectric properties were systematically measured of as-prepared nanoparticles. The structural characterization was performed using X-ray diffraction (XRD), which confirmed the crystalline nature of the synthesized ZrO2 nanoparticles with cubic crystalline phase. The average crystallite size was estimated to be 7.3 nm using the Debye-Scherrer formula. Thermal properties were analyzed through thermogravimetric analysis (TGA), revealing decomposition temperature and weight loss with temperature. Differential scanning calorimetry (DSC) provided valuable insights into the thermal behavior of the nanoparticles. Dielectric studies were conducted to evaluate the dielectric constant and loss tangent as functions of frequency. The results indicated frequency-dependent behavior of the material.
