Studying the Effect of Oxidation Reagent on Preoaration of Zinc Chromate

Abstract

Zinc Chromate was synthesised by Co-precipitation method, we have been using several oxidizing agents and found that the best one water oxygen because of the nice jamming least compared to the rest of the spectrum, The synthesized samples were characterized using X-ray powder diffraction technology (XRD).Set temperature synthesis at 250 ℃ . Muller indexes (h k l) were calculated for the production, and it was clear that, the compound crystallized according to orthorhombic lattice with following parameters

a = 5.2022 (Å), b = 8.5214 (Å), c = 6.3660 (Å)

The space group of symmetry is (R₃C).

The IR spectroscopy encourage our results during the bonding vibrations of Zn-O, Cr-O .
