Abstract

An object of the present invention is to provide hexagonal plate-shaped zinc oxide particles which can be used as a cosmetic raw material, a heat releasing filler and the like, a method for production of the same, and a cosmetic, a heat releasing filler, a heat releasing resin composition, a heat releasing grease and a heat releasing coating composition each comprising the same. Provided are hexagonal plate-shaped zinc oxide particles having hexagonal-shaped surfaces, wherein the primary particle diameter is 0.01 μm or more and the aspect ratio is 2.5 or more, and 50% or more of 250 particles in a transmission electron microscope photograph satisfy both the requirements (1) the particle has a hexagonal-shaped surface; and (2) Dmin/Dmax≧0.3, where Dmax: a length of the largest diagonal line of three diagonal lines of the hexagonal-shaped surface of the hexagonal plate-shaped zinc oxide particle; and Dmin: a length of the smallest diagonal line of three diagonal lines of the hexagonal-shaped surface of the hexagonal plate-shaped zinc oxide particle.
