Zinc oxide - Wikipedia CachedZinc oxide is an inorganic compound with the formula ZnO. ZnO is a white powder that is insoluble in water, and it is widely used as an additive in numerous materials and products including rubbers, plastics, ceramics, glass, cement, lubricants, paints, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, and first-aid tapes. Although it occurs naturally as the mineral zincite, most zinc oxide is produced synthetically. ZnO is a wide-bandgap semiconductor of the Melting point: 1,974 °C (3,585 °F; 2,247 K) (decomposes)Solubility in water: 0.0004% (17.8°C)Molar mass: 81.406 g/molChemical formula: ZnOZincite - Wikipedia CachedZincite is the mineral form of zinc oxide (Zn O). Its crystal form is rare in nature; a notable exception to this is at the Franklin and Sterling Hill Mines in New Jersey, an area also famed for its many fluorescent minerals. It has a hexagonal crystal structure and a color that depends on the presence of impurities.

Zinc oxide | ZnO - PubChem Zinc oxide, as an amphoteric material, reacts with acids to form zinc salts and with strong alkalies to form zincates; zinc oxide reacts with carbon dioxide in moist air to form oxycarbonate; acidic gases (e.g., hydrogen sulfide, sulfur dioxide, and chlorine) react with zinc oxide, and carbon monoxide or hydrogen reduce it to the metal

ZINCITE (Zinc Oxide) - Amethyst Galleries CachedMany rare minerals are found there and zincite although rare everywhere else, is far from rare there. So abundant was zincite that it was quickly exploited and became an important ore of zinc. The structure of zincite consists of tetrahedrons of ZnO4. The tetrahedrons in zincite all are oriented in one direction and produce the hexagonal (six fold rotational) symmetry.

Zinc Oxide - The Dermatology Review CachedZinc oxide derives its name from zincite the mineral from which it is produced when it is combined with oxygen molecules. It is widely used and has numerous applications because it is not water soluble, and can therefore be used in a variety of creams and make-ups.

Zincite: Mineral information, data and localities. CachedNamed "red oxide of zinc" in 1810 by Archibald Bruce as a chemical name typical of then current mineral nomenclature practice. Renamed "zincite" in 1845 by Wilhelm Karl von Haidinger. Francis Alger called this mineral "sterlingite" in 1844, while Henry James Brooke and William Hallowes Miller named this mineral "spartalite" in 1852.

Difference Between Zinc and Zinc Oxide | Compare the ... CachedSep 09, 2018 · The oxidation state of zinc in this compound is +2 and for oxygen, it is -2. It appears as a white solid that is insoluble in water. However, in nature, it occurs as the mineral Zincite; a rare mineral. This mineral contains manganese and some other impurities. Therefore, it appears as a yellow or red colour.
