Synthesis of copper chromite nanoparticles by co-precipitation methodand and study of the effect of Cu(II)/Cr(III) mole ratio, temperature and surfactant on the structure, morphology and size of it [PDF]
In this work, we used co-precipitation method for synthesis of coper chromite(CuCr2O4.CuO). Three mole ratios of Cu2+/Cr3+ (0.4, 0.7 and1.0) was used in order to investigate the effect of these mole ratios on the phase, morphology and size of particles ...
