Abstract Scope Preparation of zinc carbonate hydroxide precursor of zinc oxide powder using heating deamination precipitation was investigated. The morphology and particle size of zinc carbonate hydroxide precursor are directly related to morphology and particle size of ZnO. Therefore, it is very important to enhance capability and quality of the process for controlling the product particle size by setting the optimal reaction parameters. In this research, the influence of reaction conditions on the formation of precursor were studied, such as temperature, zinc ion and total ammonia concentrations, stirring speed, and additive dosage. The relationship between reaction conditions and morphology and particle size of precursor was confirmed by analyzing morphology and particle size of precursor at different conditions. The ZnO was obtained by decomposition of precursor prepared, based on its TGA-DTA analysis. The techniques of XRD, SEM, and LSPSA were used for the characterization of the prepared materials.
