Abstract: Zinc aluminate (ZnAl2O4) being of spinal shaped has drawn considerable attention as a catalytic material. It can be improves proprieties like high thermal stability, high mechanical resistance, crystal structure and the optical spectra [1-4]. More over zinc aluminate tends to prevent sintering of starting materials due to a strong material-support interaction. Nano sized zinc aluminate powder was prepared by heating method at 6000C sintering temperatures. Zinc sulphate (ZnSO4), alum (Na2SO4-Al2O3-24 H2O) potassium dichromate (K2Cr2O7) and urea (NH2 CO NH2) were used as starting materials. Here urea is used as a chelating agent.
Keywords: spinal zinc aluminate, picture of fired sample and SEM of samples.
