Titanium dioxide is an inorganic compound, commonly known as titanium dioxide and titanium dioxide. It is a white amorphous powder, odorless and tasteless, insoluble in water, fatty acids and other organic acids and weak inorganic acids, and slightly soluble in alkali and hot nitric acid. In nature, there are three crystal forms of titanium dioxide: rutile, anatase and brookite, among which rutile is the most stable, and the other two crystal forms will be transformed into rutile at high temperature. Its preparation methods mainly include sulfuric acid method, hydrolysis method and chlorination method.

Titanium Dioxide Has Good Optical Properties and Dazzling Brilliance

The reason why titanium dioxide is highly respected, first of all, benefits from its excellent optical properties. It has a high refractive index, the refractive index of rutile titanium dioxide can reach about 2.7, and that of anatase titanium dioxide can reach about 2.55, which makes it possible to effectively change the propagation path of light when it is mixed with other substances, thus showing a strong hiding power. This is like putting an invisible "hood" on an object, making it difficult for the color or object below to show.

Take the paint as an example. After adding titanium dioxide, only a thin layer is needed to completely cover the surface of the coated object, so that it presents a pure and white appearance. Moreover, titanium dioxide has excellent reflection and scattering ability to ultraviolet rays, which can resist ultraviolet rays like a small shield and provide good sun protection for the materials it uses.

Titanium Dioxide: The Darling of Coatings Industry, Drop-Dead Gorgeous

In the field of architecture, ti02 powder is a key component in coatings. For example, those skyscrapers that soar into the sky often contain titanium dioxide in their exterior wall paint, which not only makes the appearance of the building brighter and whiter, but also effectively resists the erosion of ultraviolet rays, prevents the walls from fading and powdering due to long-term exposure, and prolongs the service life of the building.

In automobile coatings, tio2 powder can also be seen everywhere. It can give the car body bright colors and high gloss, make the car shine in the sun, and also have good weather resistance, even in bad weather conditions, it can maintain the integrity and beauty of the paint surface.

In terms of industrial coatings, many metal products and mechanical equipment can be well protected against rust and corrosion after being coated with coatings containing titania tio2, ensuring their stable performance during long-term use.
