Zinc oxide is a constituent of cigarette filters for removal of selected components from tobacco smoke. A filter consisting of charcoal impregnated with zinc oxide and iron oxide removes significant amounts of HCN and H2S from tobacco smoke without affecting its flavor.; Zinc oxide is an amphoteric oxide. It is nearly insoluble in water and alcohol, but it is soluble in (degraded by) most acids, such as hydrochloric acid:; Zinc oxide is an inorganic compound with the formula ZnO. It usually appears as a white powder, nearly insoluble in water. The powder is widely used as an additive into numerous materials and products including plastics, ceramics, glass, cement, rubber (e.g. car tyres), lubricants, paints, ointments, adhesives, sealants, pigments, foods (source of Zn nutrient), batteries, ferrites, fire retardants, first aid tapes, etc. ZnO is present in the Earth crust as a mineral zincite; however, most ZnO used commercially is produced synthetically.; Zinc white is used as a pigment in paints and is more opaque than lithopone, but less opaque than titanium dioxide. It is also used in coatings for paper. Chinese white is a special grade of zinc white used in artists' pigments. Because it reflects both UVA and UVB rays of ultraviolet light, zinc oxide can be used in ointments, creams, and lotions to protect against sunburn and other damage to the skin caused by ultraviolet light (see sunscreen). It is the broadest spectrum UVA and UVB absorber that is approved for use as a sunscreen by the FDA, and is completely photostable. It is also a main ingredient of mineral makeup.; ZnO is a relatively soft material with approximate hardness of 4.5 on the Mohs scale. Its elastic constants are smaller than those of relevant III-V semiconductors, such as GaN. The high heat capacity and heat conductivity, low thermal expansion and high melting temperature of ZnO are beneficial for ceramics.ActivoxActivox bActox 14Actox 16Actox 216Akro-zinc Bar 85Akro-zinc bar 90AmaloxAzo-55TTAzo-66TTAzo-77TTAzodoxAzodox-55Azodox-55TTBlanc de zincC-Weiss 8C.I. pigment white 4Cadox XX 78CanfelzoChinese whiteCI Pigment white 4Colloidal zinc oxideDeceloxDense zinc oxideDenzoxElectox 2500ElectroxElectrox 2500Emanay zinc oxideEMAREntroxExtroxFelling zinc oxideFelzodoxFinex-25Flores de zinciFlowers of zincFotofaxGarozincGIAP 10Green seal-8Hubbuck's whiteHubbucks whiteK-zincKadox 15Kadox 72Kadox-25Ken-zincLeaded zinc oxideLow purity zinc oxideMethiconeMicroxNo-genolNogenolOctocure 553OutmineOxide, zincOxido de cincOxyde de zincOzideOZLOPaste, lassar'sPermanent whitePhilosopher's woolPhotozincPigment white 4Powder base 900Protox 166Protox 168Protox 169Protox type 166Protox type 167Protox type 168Protox type 169Protox type 267Protox type 268Red Seal 9RuboxRvpaqueSnow whiteTertiary zinc oxideUnichem zoVandem vacVandem vocVandem VPCVita zincWhite seal-7Zinc gelatinZinc monoxideZinc oxide (JP15/USP)Zinc oxide (TN)Zinc oxide (zno)Zinc oxide [usan]Zinc oxide fumeZinc oxide No. 185Zinc oxide No. 318Zinc oxide transparentZinc oxide, acsZinc oxidesZinc whiteZinca 20Zinci oxicumZinci oxydumZinciteZincoidZink whiteZinkoxidZinkoxyd activZinoxZiradrylZNOOZn81.40879.9240612zinc(2+) ion oxidandiidezinc(2+) ion oxidandiide1314-13-2[O--].[Zn++]InChI=1S/O.Zn/q-2;+2RNWHGQJWIACOKP-UHFFFAOYSA-N belongs to the class of inorganic compounds known as transition metal oxides.
