Simple and cost-effective solution combustion method is used to synthesize nano powders of ZrO₂ and ZrTiO₄. The structural and morphological analysis was done by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Results revealing the phase confirmation and structure of synthesized samples. Dielectric properties of the synthesized ZrTiO₄ powder dominates the synthesized ZrO₂ having superior dielectric constant (ɛʹ = 50), Low dielectric loss and enhanced conductivity (σac = 2.75 x 10-4 Scm^-1) at room temperature. The humidity sensing properties for ZrTiO₄ shows good linear behavior compare to ZrO₂.
