Nanometer-sized ZnO powders have recently attracted considerable attention in ceramic semiconducting, optoelectronic, and cosmetic industry owing to their useful electronic and physical features. Recently, a lot of research has been tried to find out the relation between process parameters and physical features for ZnO nano-powder. In this study, the nano-structural and physical features of the ZnO nano-powders (ZONP), which were prepared by hydrothermal method, were investigated as a function of the concentration and the kinds of starting materials, precipitants, and pH conditions. The size of ZnO particle was sensitively related with the condition of the reaction materials. The structural features and the shape of particle, such as spherical, hexagonal, quasi-cubic, needle type, could be controlled by the variation of process parameters. |
