酸化亜鉛

化学的特性亜鉛酸化物は化学式でZnOと表される無機化合物です白色の固体であり水には溶けにくい性質を持っています自然界では亜鉛華としても知られており日焼け止めクリームなどの化粧品からゴムの製造さらには食品添加物まで幅広い用途で利用されています

化学的特性Zinc oxide is an amorphous, white or yellowish-white powder. It is a fine white powder that becomes yellow at temperatures above 3000℃. It is an amphoteric oxide that reacts with acids and dissolves in alkaline solution with formation of zincates. Its density and oil absorption value are 5.6 g/cm3 and 10-25 g oil/100 g ZnO, respectively.

使用zinc oxide has been used to protect, soothe, and heal the skin. Zinc oxide provides an excellent barrier to the sun and other irritants. It is somewhat astringent, anti-septic, and anti-bacterial. When used in sunscreen preparations, it provides both uVA and uVB protection, and can contribute to and/or increase SPF. At the appropriate particle size, zinc oxide is transparent in the visible light spectrum but opaque in the uVC ranges, thereby avoiding a whitening effect when incorporated into sunscreen preparations. Zinc oxide is included on the FDA’s list of approved sunscreen chemicals. It demonstrates an impressive synergistic effect when combined with organic sunscreens. Zinc oxide is also used when a white color is desired for a product. It is obtained from zinc ore, a commonly found mineral, and is relatively non-allergenic.

一般的な説明Crude zinc oxide is a yellow-gray granular solid with no odor. Zinc oxide has a specific gravity of 4.4. Zinc oxide is insoluble in water. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. Prolonged inhalation of the dust may result in metal fume fever with symptoms of chills, fever, muscular pain, nausea and vomiting.

製造方法Zinc oxide is obtained as an intermediate in recovering zinc from minerals (See Zinc, Recovery). The oxide is prepared by vaporizing zinc metal and oxidation of the zinc vapors with preheated air (French process). The oxide can be produced by other processes. Another method involves roasting franklinite and other ores with coal and then oxidizing the product in air.

定義本品は、直鎖状のモノメチルポリシロキサンであり、次の化学式で表される。

定義zinc oxide: A powder, white whencold and yellow when hot, ZnO; r.d.5.606; m.p. 1975°C. It occurs naturallyas a reddish orange ore zincite,and can also be made by oxidizinghot zinc in air. It is amphoteric,forming zincates with bases. It isused as a pigment (Chinese white) and a mild antiseptic in zinc ointments.An archaic name is philosopher’swool.
