A MEHTOD FOR AUTO COMBUSTION SYNTHESIS OF NANO ZNO POWDER

摘要

A method for autocombustion synthesis of nano ZnO powder which comprises the following steps: mixing aqueous solutions of zinc nitrate and citric acid in the molar ratio 1:1; iheating the mixture at 80°C to obtain a gel; iiiallowing auto combustion of the gel to obtain a fluffy loose powder as-burnt ash; and iv) calcining the as-burnt ash at 400°C.
