A Facile Aqueous Sol–Gel Process for the Synthesis of Alumina–Lanthanum Phosphate Nanocomposite
Abstract:A facile aqueous sol–gel process is being reported for the first time for the synthesis of alumina–lanthanum phosphate (Al2O3–LaPO4) nanocomposite. X-ray diffraction (XRD) analysis confirms the absence of any reactive phase even after heating to 1600°C. Microstructural analysis reveals a mutually controlled grain growth and the XRD analysis shows that the crystallite size of LaPO4 is in the range of 5–7 nm, indicating the exceptional inhibition of grain growth as well as the nanostructure of the sintered composite.
