Structural and electrical properties of novel Mg0.9+0.5yZn0.4AlyZr1.6−y(PO4)3 ceramic electrolytes synthesized via nitrate sol–gel method

Magnesium-based Nasicon-type compounds with formula Mg0.9+0.5yZn0.4AlyZr1.6−y(PO4)3, (0.0 ≤ y ≤ 0.4) were prepared by the nitrate sol–gel method and characterized by X-ray diffraction, particle size analyser, scanning electron microscopy, energy-dispersive X-ray spectroscopy and impedance spectrosco...
