EFFECT OF FUELS ON THE COMBUSTION SYNTHESIS OF NiAL۲O۴ 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 ۱۴ nm. From the particle size analysis, it was found that the ۵۰ % of the particles lie below ۳۰µm. 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 applied۲O۴ spinels by low temperature combustion technique using glycine and urea as fuels.۲O۴ particles and the crystallite sizes were
