Abstract

Combustion synthesis has been developed as a simple and economically viable technique for the preparation of composites, nanomaterials and intermetallics. In this paper, by combining two methods (milling and combustion synthesis) the effects of milling time and combustion furnace environment on the synthesis of the mixture consists of aluminium and industrial Zirconia powders was investigated. By milling, the average crystallite size of powders was reduced to 20nm. Particle morphology and powder composition were observed by SEM and were analysed by X-ray diffraction respectively..
