Abstract:
A facile aqueous sol-gel process is being reported for the first time for the synthesis of alumina-lanthanum phosphate (Al(2)O(3)-LaPO(4)) nanocomposite. X-ray diffraction (XRD) analysis confirms the absence of any reactive phase even after heating to 1600 degrees C. Microstructural analysis reveals a mutually controlled grain growth and the XRD analysis shows that the crystallite size of LaPO(4) is in the range of 5-7 nm, indicating the exceptional inhibition of grain growth as well as the nanostructure of the sintered composite.
