Read： 832 Time：20months ago Source：Transform the World with Simplicity

Titanium oxide is an important raw material for chemical production and has a wide range of applications. This article will detail the properties and uses of titanium oxide.

1. the properties of titanium oxide

titanium oxide is a white solid powder with high refractive index and high chemical stability. It can remain stable at high temperatures and is insoluble in water, dilute acid and alkali solutions. The crystal structure of titanium oxide is mainly of three types: anatase, rutile and brookite. Among them, anatase type and rutile type are two common crystal structures.

titanium oxide has excellent optical properties, has strong photocatalytic activity, and can decompose organic matter and reduce heavy metal ions under light conditions. In addition, titanium oxide also has good ultraviolet absorption properties and is often used to make sunscreen and cosmetics.

2. the use of titanium oxide

1. catalyst

titanium oxide as an excellent photocatalyst, is widely used in the field of environmental protection. In wastewater treatment, titanium oxide can effectively remove pollutants in water by photocatalytic degradation of organic matter, reduction of heavy metal ions, etc. In addition, titanium oxide can also be used in automobile exhaust treatment to convert harmful substances in exhaust gas into harmless substances.

2. ultraviolet absorber

titanium oxide has strong ultraviolet absorption properties, is widely used in cosmetics, skin care products and sunscreen and other products. It can absorb ultraviolet rays and protect the skin from ultraviolet rays.

3. Pigment

Titanium oxide as an important white pigment, is widely used in coatings, plastics, paper and other industries. It has good hiding power and tinting power, and can improve the whiteness and brightness of the product.

4. Solar Cell

Titanium oxide is widely used in solar cells as a photoanode material. It can absorb sunlight and produce photo-generated electrons and holes, thereby converting solar energy into electricity.

In short, titanium oxide, as an important raw material for chemical production, has a wide range of applications. Its excellent properties and uses make titanium oxide in the chemical industry, environmental protection, medical, cosmetics and other industries have been widely used, for people's lives and production has brought great convenience and development.
