Abstract
In this study, a gel combustion method was used to prepare ZnO nano powder. Zinc nitrate, nitric acid, and different fuels of glycine, urea, and citric acid were used with various ratios of fuel to salt and different primary pH values, followed by calcinations at temperatures of 400-600 oC. The results showed that using citric acid, fuel to raw material ratio of 0.5, a neutral pH, and a calcination temperature of 500 oC were the optimum conditions to prepare ZnO nano powder of about 30 nm.
Keywords: Nano powder, Zinc oxide, Gel combustion, Glycine, Citric Acid.
