Synthesis of lanthanum aluminate via the ethylenediaminetetraacetic acid gel route

LaAlO3 was successfully synthesized by the ethylenediaminetetraacetic acid gel route. The precursors and the derived powders were characterized by differential thermal analysis, thermogravimetric analysis, Fourier transform infrared spectroscopy and X-ray diffraction. Well-crystallized LaAlO3 phase was obtained at 800 °C for 2 h, without formation of any intermediate phase.
