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°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.
