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.

Cosmetics:

Zinc oxide is used in cosmetics, including foundations, lotions and creams, because it provides a smooth, matte finish and acts as a UV blocker.

Drugs:

Due to its soothing and protective properties on the skin, it is used in some pharmaceutical products, such as diaper rash creams and ointments.

Rubber manufacturing:

Zinc oxide is a common ingredient in the production of rubber products. It aids in the vulcanization process, improving the rubber's elasticity and durability.

Ceramic:

In the ceramic industry, zinc oxide is used as a flux to lower the melting temperature of the glaze so that it adheres better to the ceramic surface.

Paints and Paints:

It is used as a pigment in white paints to provide opacity and brightness. It is also used as a coating for wood, paper, and other materials.

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.

Textiles:

In textiles, zinc oxide nanoparticles are sometimes used for their antimicrobial and UV-blocking properties.

Catalysis:

ZnO is used as a catalyst in certain chemical processes.
