| Abstract | ||
| This study aims to synthesize a nanocrystalline alumina doped with chromia by using aluminum foil waste as a source of alumina and chromium nitrate non-hydrate as a source of chromia. Chromia doped alumina was prepared by co-precipitation method and fired at different temperatures. The co-precipitated powder formed thereby has been examined by XRD, FTIR and TEM techniques. X-Ray diffraction patterns show a good crystalline of the powder with very sharp and neat peaks at high temperatures more than 1000°C. The results of FTIR analysis confirmed the getting of solid solution of alumina chromia. TEM photographs show the good distribution of the particles, which have an average particle size of 1-3 nm at low temperature. | ||
