Titanium Dioxide (TiO2) is a white inorganic compound that sees significant use as a white pigment, especially in the manufacture of paints, coatings, printer ink and plastics, as well as in the production of papers, pharmaceuticals, food products and cosmetics, among others. Choosing the type of titanium dioxide that works for you will mostly depend on its ultimate use and the types and characteristics of the titanium dioxide.

What is titanium dioxide?
TiO2 is composed of one titanium atom and two oxygen atoms, and its CAS registry number is -67-7. It is quite good at scattering light, offering luminosity (what we call a high refractive index) without being toxic or reactive, allowing for intensifying the whiteness and shine of many materials in a safe manner. The shine, chromatic intensity, opacity and whiteness that it offers are unique.
TiO2&#;is considered to be chemically inert, which means that it does not react with other chemicals.
Both its melting point&#;(&#;°C / °F) and its boiling point (&#;°C / °F) are extremely high, which means that it is found in nature in a solid state and is insoluble in water even as a particle.
TiO2 Varieties
Among the existing varieties of TiO2, the most conventional forms are RUTILE, which sees the most widespread use worldwide, and ANATASE, which sees more use in the pharmaceutical, cosmetics and food industry.
Titanium Dioxide production methods
There are two methods to produce TiO2: a sulfate process and a chloride process.
In the sulfate process, the mineral is dissolved in sulfuric acid and extracted as sulfate salts, and is then subjected to hydrolysis, calcination and a milling stage, where any remnant of sulfuric acid is broken down and crystals of the required size are formed. In the chloride process, chlorine is used instead of sulfuric acid, where Rutile is transformed into titanium chloride, and the titanium chloride oxidizes, thereby obtaining it through a more affordable process.
Main Characteristics of Titanium Dioxide
The various forms of TiO2 are characterized by usually being subjected to a surface treatment that improves their properties in regard to dispersibility, coating capabilities, surface compatibility and low oil absorption. These treatments are commonly inorganic, with the use of alumina, silica and zinc.
When choosing a variant of titanium dioxide you must analyze the following:

Titanium dioxide, also known as rutile titanium dioxide, is a white, powdery pigment used in a variety of industries, including paint, plastics, paper, and cosmetics. It is a naturally occurring mineral that is mined from the earth and then processed into a fine powder. Titanium dioxide is a popular choice for many applications due to its excellent light-scattering properties, which make it an ideal white pigment.
When choosing the right rutile titanium dioxide for your application, there are several factors to consider. First, you need to determine the type of application you are using the pigment for. Different types of titanium dioxide are better suited for different applications. For example, anatase titanium dioxide is better suited for use in paints and coatings, while rutile titanium dioxide is better suited for use in plastics and paper.
Next, you need to consider the particle size of the titanium dioxide. The particle size of the pigment will affect the opacity and brightness of the final product. Generally, smaller particles will produce a brighter, more opaque finish, while larger particles will produce a more transparent finish.
Finally, you need to consider the purity of the titanium dioxide. The purity of the pigment will affect the color and opacity of the final product. Generally, higher purity titanium dioxide will produce a brighter, more opaque finish, while lower purity titanium dioxide will produce a more transparent finish.
When selecting the right rutile titanium dioxide for your application, it is important to consider all of these factors. By doing so, you can ensure that you are getting the best possible product for your needs. Additionally, it is important to purchase your titanium dioxide from a reputable supplier to ensure that you are getting a high-quality product.
In conclusion, choosing the right rutile titanium dioxide for your application is an important decision. By considering the type of application, particle size, and purity of the pigment, you can ensure that you are getting the best possible product for your needs. Additionally, it is important to purchase your titanium dioxide from a reputable supplier to ensure that you are getting a high-quality product.
