Abstract
(EN) Provided is zinc oxide powder in which the BET specific surface area is 8 m2/g to 65 m2/g, the apparent specific volume measured by a loose packing method is 1.0 mL/g to 7.5 mL/g, and the value obtained by dividing the apparent specific volume (mL/g) measured by the loose packing method by the apparent specific volume (mL/g) measured by a tapping method (apparent specific volume measured by loose packing method/apparent specific volume measured by tapping method) is 1.50 to 2.50.
(FR) L'invention concerne une poudre d'oxyde de zinc qui présente une surface spécifique BET supérieure ou égale à ８ｍ２／ｇ et inférieure ou égale à ６５ｍ２／ｇ, un volume spécifique apparent selon un procédé de dépôt est supérieur ou égal à １,０ｍＬ／ｇ et inférieur ou égal à ７,５ｍＬ／ｇ, et une valeur obtenue par division dudit volume spécifique apparent （ｍＬ／ｇ） selon le procédé de dépôt par le volume spécifique apparent （ｍＬ／ｇ）selon un procédé de tassement (volume spécifique apparent selon procédé de dépôt / volume spécifique apparent selon procédé de tassement) supérieure ou égale à １,５０ et inférieure ou égale à ２,５０.
(JA) ＢＥＴ比表面積が８ｍ２／ｇ以上６５ｍ２／ｇ以下、静置法による見掛け比容が１．０ｍＬ／ｇ以上７．５ｍＬ／ｇ以下、および、前記静置法による見掛け比容（ｍＬ／ｇ）をタップ法による見掛け比容（ｍＬ／ｇ）で除した値（静置法による見掛け比容／タップ法による見掛け比容）が１．５０以上２．５０以下である、酸化亜鉛粉体。
