Surface morphology and crystallinity of metal oxides in nickel-cobalt binary system

The effect of composition on nickel cobaltites prepared by co-precipitation was investigated. Various compositions were synthesised under different heat treatment conditions. The formation mechanism, lattice parameter and crystallite size were determined by various techniques. X-ray dffraction (XR...
