| Abstract | ||
| Nano crystalline powder of the System Cu-Al-O have been prepared by Sol-Gel technique, copper nitrate and aluminum nitrate have adopted as raw materials for the reaction, and subsequently solid state reactions have used to synthesize different compounds and phases at the calcination stage. Effects of calcination temperature and time in the range 800-1100oC and 1hr-6hr respectively have been investigated. XRD results show that the system have a multiphase and it depends on the calcination time and temperature, the higher the temperature and time the higher the percentage of the compound CuAlO2, whereas the SEM microscopy show that the Nano powder have particle size of 40nm, and Raman spectroscopy reveals the presence of Eg and A1g modes which belong to the structure CuAlO2. The work emphasize that the control of the technique parameters could provide high degree of control on the final required phases and structures. | ||
