PARTICULES D'OXYDE DE ZINC EN FORME DE PLAQUE HEXAGONALE, PROCÉDÉ POUR LES PRODUIRE ET MATIÈRE COSMÉTIQUE, CHARGE À DISSIPATION DE CHALEUR, COMPOSITION DE RÉSINE À DISSIPATION DE CHALEUR, GRAISSE À DISSIPATION DE CHALEUR ET COMPOSITION DE REVÊTEMENT À DISSIPATION DE CHALEUR LES CONTENANT
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, whereinthe primary particle diameter is 0.01 µm or more and the aspect ratio is 2.5 or more, and50% or more of 250 particles in a transmission electron microscope photograph satisfy both the requirements (1) and (2) :(1) the particle has a hexagonal-shaped surface； and(2) Dmin/Dmax ≥ 0.3, whereDmax: a length of the largest diagonal line of three diagonal lines of the hexagonal-shaped surface of the hexagonal plate-shaped zinc oxide particle； andDmin: a length of the smallest diagonal line of three diagonal lines of the hexagonal-shaped surface of the hexagonal plate-shaped zinc oxide particle.
