Zinc oxide is an inorganic compound with the formula ZnO. It is a white powder that is insoluble in water. ZnO is present in the Earth's crust as the mineral zincite. That being said, most ZnO used commercially is synthetic.

Zinc oxide is commonly found in medical ointments where it used to treat skin irritiations. In more recent times zinc oxide has transcended to use in semiconductors, concrete use, ceramic and glass compositions and even cigarette filters.

Basic properties of Zinc Oxide are tabulated as follows:

It might come as a shock but over 50% of the Zinc Oxide used is in the rubber industry. ZnO along with stearic acid is used in the vulcanization of rubber to produce such things as tires, shoe soles, and even hockey pucks.

A very important use is that Zinc Oxide is widely used as the buffer layer in CIGS (Copper Indium Gallium Selenide) solar cells. Some current experiments are focusing on the effect of the thickness of ZnO on maximum power output for the cells.

Another main use in in concrete manufacture. The addition of Zinc Oxide aids the processing of concrete and also improves water resistance.

Zinc oxide also has antibacterial and deodorizing peroperties. For this reason it is employed in medical applications such as in baby powder and creams to treat conditions such as diaper rash, other skin irritations and even dandruff. Due to its reflective properties it is also used in sunblocks and can often be seen on the nose and lips of lifeguards at the beach.

Zinc oxide is also used in:

The future for high quality Zinc Oxide is certainly going to be fascinating. The potential advances for non-medicinal applications even surpass that of the current medicinal uses. Zinc Oxide Nanorod Sensors, Spintronics, and Piezoelectricity are all very promising fields and ones to keep an eye on in the not too distant future.

This article provides an end-of-life assessment of lithium-ion batteries, focusing on the recycling of an ever-growing amount of spent Li-Ion batteries in order to work toward a sustainable and circular approach to battery use and reuse.

Corrosion is the degradation of an alloy caused by its exposure to the environment. Corrosion deterioration of metallic alloys exposed to the atmosphere or other adverse conditions is prevented using a variety of techniques.

Due to the ever-increasing demand for energy, the demand for nuclear fuel has also increased, which has further created a significant increase in the requirement for post-irradiation examination (PIE) techniques.
