The role of ZnO additions on physical and electrical properties ofxZnO-(40-x) Fe2O3-60P2O5, with x = 0, 2.5, 5.0, 7.5, and 10.0 (mol %) glasses arereported. The trends of bulk and powder densitieswere founddecreased with the increasing amountof ZnOcontent. The porosity data suggestedthat all glasses are dense with the percentage value below 0.4 %. The XRD and backscattered electron SEM image confirmed that all samples transform to homogeneous glass materials without precipitation of any crystalline phases. The electrical properties of iron phosphate and zinc iron phosphate glasses were measured by impedance spectroscopy from 1MHz to 1GHz. The dielectric constant and dissipation factor of iron phosphate glasses werefound decreased with the increasing content of ZnO. The iron phosphate glasses with increasing ZnO additions shown strong insulator behaviour of which suitable for insulating glass sealant applications.
