(57) [Summary] [Composition] A zinc salt solution and a solution containing ammonium ions or a compound that decomposes to generate ammonium ions are mixed, and crystals or flaky hydroxides of flaky basic zinc salt are subjected to a neutralization reaction. In a method for producing flaky zinc oxide powder by precipitating zinc crystals, filtering and drying if necessary, and then calcining, the neutralization reaction is carried out in the presence of a water-soluble organic substance. Method for producing flaky zinc oxide powder. [Effect] It is possible to provide a flaky zinc oxide powder having a narrow particle size distribution with an arbitrary average particle size and excellent in visible light transmittance, ultraviolet ray shielding ability, hiding ability, filling property and the like. |
