Zinc oxide is a white powder which is insoluble in water and it is is an 1310-73-2 inorganic compound with ZnO. It is widely used in our lives. For example, it is is widely used as an additive into numerous materials and products including plastics, ceramics, glass, lubricants, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, first aid tapes and so on. ZnO is present in the Earth's crust as the mineral zincite.The applications of zinc oxide powder are numerous. Most applications exploit the reactivity of the oxide as a precursor to other zinc compounds.
In materials science, ZnO is a wide-bandgap semiconductor of 1314-13-2 the II-VI semiconductor group (since zinc and oxygen belong to the 2nd and 6th groups of the periodic table, respectively). The native doping of the semiconductor (due to oxygen vacancies) is n-type. This semiconductor has several favorable properties, such as wide bandgap , high electron mobility and good transparency and so on.
It is difficult to trace the usage of zinc oxide, because a various 107-13-1 of zinc compounds were widely used by humans in the early times, with various processed and unprocessed forms, as a paint or medicinal ointment, but their exact composition is uncertain. However, humans were not sure zinc oxide'composition.
