Abstract: These Nanocomposites are synthesized by Sol-gel process named as Alumina and copper Alumina. They are calcined at 600⁰C. In this High energy ball milling and High temperature sintering process was introduced for these calcined composites. XRD and SEM images are obtained for them to characterize. After the High Energy Ball Milling process the same samples are sintered at 300⁰C and obtained XRD and FTIR images to calculate crystalline size and lattice strain (%). The other process via sol-gel was sintered at 1000⁰C and characterized by XRD and FTIR techniques. The following conclusions were drawn as HEBM is not suitable to form a HEBM is not suitable to form a crystalline phase whereas low temperature sintering after milling is favoured for crystalline phase for both pure Alumina and Copper Alumina Nanocomposites. High temperature sintering is also a possible technique for the formation of pure alumina and copper aluminate nanocomposite CuAl2O4 spinel form is obtained.
