The aim of said study was to obtain nanostructured La2ZnO4 through self combustion synthesis using lanthanum nitrate, znic nitrate as precursors and glycine as a fuel, without the subsequent heat treatments after synthesis. The temperature variation with respect to a sample with constant molar ratio was investigated. The crystallinity ( phases present and crystallite size: estimated by single-line method ) of the product obtained was determined by X-ray diffraction (XRD) measurement, thermogravimetric analysis(TG-DTA),scanning electron microscope(SEM),and transmission electron microscopy (TEM). The synthesis method facilitated the production of Perovskite La2ZnO4 with crystallite size between 18-40 nm. The superhydrophilicity of the sintered oxides was investigated by wetting experiments, by the sessile drop technique, were carried out at room temperature in air to determine the surface and interfacial interactions.
