Abstract Zinc oxide was prepared by hydrothermal method with zinc nitrate as zinc source and ammonia, sodium
hydroxide and sodium carbonate as precipitant. The crystal growth of the precursors obtained from different precipitants
and their hydrothermal products were studied.The products were characterized by X-ray diffraction and transmission
electron microscopy. The results show that basic zinc carbonate can be obtained from the precursor formed
with sodium carbonate as precipitant by hydrothermal method, while zinc oxide can be obtained from the precursor
formed with ammonia and sodium hydroxide as precipitants by hydrothermal method. The growth laws of zinc oxide
crystals prepared with ammonia and sodium hydroxide as precipitants conform to different linear growth relationships.
Their crystals have different product morphologies.
