EFFECT OF FUELS ON THE COMBUSTION SYNTHESIS OF NiAL2O4 SPINEL PARTICLES

Abstract: as magnetic materials, semiconductors, pigments, catalysts, refractories and electronic ceramics. In this paper, wereported the preparation of NiAlThe resulting powder was chracterized by XRD, particle size analysis and SEM. The XRD patterns show that thecombustion technique was excellent to prepare single – phased cubic NiAlfound to be around 14 nm. From the particle size analysis, it was found that the 50 % of the particles lie below 30µm. The micrographs show the formation of fluffy agglomerates composed of fine particles.Spinels constitute an advanced group of materials with great technologial appeal, being able to be applied2O4 spinels by low temperature combustion technique using glycine and urea as fuels.2O4 particles and the crystallite sizes were
