(57) [Problem] To provide a method for producing zinc oxide fine particles having high transparency to visible light and excellent ultraviolet shielding properties. SOLUTION: Carbon dioxide gas is introduced into a water slurry containing zinc oxide to generate basic zinc carbonate, and the obtained basic zinc carbonate slurry is subjected to fluidized bed drying, medium fluidized bed drying, flash drying and spraying. After drying, the dried basic zinc carbonate is thermally decomposed to obtain zinc oxide fine particles. |
