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.
