Abstract: The effect of the anionic composition on the preparation of powder material in the ZnO – SnO2, system by the sol-gel method has been investigated. It was found that the best composition of zinc orthostannate is obtained using zinc sulfate and tin (IV) chloride. According to the data of X-ray phase analysis, the optimum temperature for the synthesis of the material is 1050 °C.

Zinc stannate (ZnSnO3) ceramic nanoparticles were synthesized via a sol-gel polymeric technique utilizing polyacrylic acid as a template polymer. The effect of pH during the synthesis process was investigated by preparing the ZnSnO3 nanoparticles at pH 3 and 8. The structural, molecular, morphological, optical, and dielectric properties of the synthesized ZnSnO3 nanoparticles were thoroughly characterized using FTIR, XRD, SEM, and TEM, with optical and dielectric measurements. FTIR and XRD analyses confirmed the phase purity of the synthesized ZnSnO3 nanoparticles, which exhibited an orthorhombic perovskite crystal structure. As observed in the SEM and TEM images, the ZnSnO3 nanoparticles prepared at pH 8 displayed a more defined cubic crystalline morphology, with an average particle size of 128 nm. The optical properties of the ZnSnO3 nanoparticles showed a high absorption edge in the UV region for both pH conditions. The calculated bandgap energies were 3.67 eV for pH 3 and 3.57 eV for pH 8. The dielectric properties at pH 3 and 8 exhibited a low dielectric constant (ε′ = 4 and 5, respectively) and very low dielectric loss (tan δ = 0.1 and 0.06, respectively) at 1 MHz. These exceptional optical and dielectric properties make the prepared ZnSnO3 nanoparticles a promising material for various applications. Graphical Abstract
