What is zinc oxide used for?

Zinc oxide (ZnO) is a white powdery compound commonly used in a variety of applications due to its multifunctional properties. Zinc oxide is a compound composed of zinc and oxygen, with the chemical formula ZnO. It occurs naturally as zinc ore but is often produced synthetically for commercial purposes. It is a white powder with a wide bandgap, making it highly reflective and useful in applications requiring opacity.

Uses of zinc oxide

Sunscreen:

One of the most common uses of zinc oxide is in sunscreen. It effectively protects against UVA and UVB rays by reflecting and scattering sunlight. It is a top choice among sunscreens due to its broad spectrum coverage and low skin absorption.

Electronic products:

Due to its semiconducting properties, zinc oxide is used in a variety of electronic applications, such as varistors, sensors, and as transparent conductors in thin-film solar cells.

Battery:

Zinc oxide is used in some types of batteries, including zinc-air batteries.
