Synthesis, characterization and band gap studies of ƞ-Al₂O₃, ƞ-Al₁.₉Fe₀.₁O₃ and ƞ-Al₁.₉Ni₀.₁O₃ nanostructured materials obtained via selfpropagating combustion (SPC) method / Mawar Hazwani Jasimin

ƞ-Al₂O₃ is one of the metastable phases of aluminum oxide and known to be a very important support material for heterogeneous catalysts used extensively in the chemical industry. This phase is not easy to obtain. In this research, the ƞ-phase is synthesized using a novel method, the self-propagating...
