沉淀法制备氧化锌粉体

Abstract

Abstract: The precursor，basic zinc carbonate was obtained by precipitation method with ZnSO4 and Na2CO3 as raw materials. Then ZnO powders were prepared after pyrolysis of precursor.Precursor and ZnO powders were characterized and analyzed by TG-DTG-DTA，XRD，IR，and SEM respectively.Results showed that the precursor was Zn4（OH）6CO3；pure ZnO can be both prepared by water and ethylene glycol as solvents and by PEG as dispersant；and the morphology and dispersibility of ZnO could be improved and agglomeration could be avoided with ethylene glycol as solvent and PEG as dispersant.

Key words: zinc oxide, preparation, precipitation method
