Spinel Crystals

X-ray diffraction (XRD) of nickel aluminate showed its structural properties such as crystallite size, lattice constant, unit cell volume and X-ray density. The nano-sized nickel aluminat (NiAl2O4) crystals were prepared in this study. The morphological properties and the surface concentration of elements involved in the spinel NiAl2O4 solid were studied by Scanning electron micrographs (SEM) and Energy dispersive X-ray (EDX) techniques. The results showed formation of single phase of nano-crystalline nickel aluminate with spinel structure. The nature of the as synthesized powders was spongy and fragile
