Citric Acid ComplexLegal System for ZnO Powder andCharacterization
Abstract：Choosing zinc nitrate as the starting material, citric acid as complexing agent, and using sol-gel method make high purity zinc oxide powder. Through the X ray diffraction, scanning electron microscope, laser diffraction particle size analyzer ,the powder of phase composition, morphology and particle size distribution of the characterization, and the citric acid and Zn2+ complexation reaction mechanism was analyzed The results show that, using citric acid complex legal system in 450℃ can prepare the hexagon wurtzite structure of ZnO powder materials; The powder which is made in 550℃ have high crystallinity, shape a rules, and particle size distribution is more narrow. The concentration distribution is 0. 5-1.2 um.
