Zinc oxide is an inorganic compound with the formula ZnO. ZnO is
a white powder that is insoluble in water, which is widely used as
an additive in numerous materials and products including plastics,
ceramics, glass, cement, lubricants, paints, ointments, adhesives,
sealants, pigments, foods (source of Zn nutrient), batteries,
ferrites, fire retardants, and first aid tapes. It occurs naturally
as the mineral zincite but most zinc oxide is produced
synthetically.
In materials science, ZnO is a wide-bandgap semiconductor of the
II-VI semiconductor group (since oxygen was classed as an element
of VIA group (the 6th main group, now referred to as *6th) of the
periodic table and zinc, a transition metal, as a member of the IIB
(2nd B), now *2th, group). The native doping of the semiconductor
(causes are as yet unknown) is n-type. This semiconductor has
several favorable properties, including good transparency, high
electron mobility, wide bandgap, and strong room-temperature
luminescence. Those properties are used in emerging applications
for transparent electrodes in liquid crystal displays, in
energy-saving or heat-protecting windows, and in electronics as
thin-film transistors and light-emitting diodes.
Applications:
The applications of zinc oxide powder are numerous, and the
principal ones are summarized below. Most applications exploit the
reactivity of the oxide as a precursor to other zinc compounds. For
material science applications, zinc oxide has high refractive
index, high thermal conductivity, binding, antibacterial and
UV-protection properties. Consequently, it is added into materials
and products including plastics, ceramics, glass, cement, rubber,
lubricants, paints, ointments, adhesive, sealants, pigments, foods,
batteries, ferrites, fire retardants, etc
