Titan Dioxide










Titanium dioxide (TiO2) is a known food colorant with the food additive code E171. Titanium dioxide, used as a colorant, is also known as titanium white.

Raw titanium dioxide is obtained through purification of titanium tetra chlorine. This process is carried out in two types as sulfate and chlorine processes. Commercial titanium dioxide is not pure, it is a synthetic pigment. The biggest expense in paint manufacturers ' purchasing budgets is titanium dioxide. Its use is mainly in building/construction (50% of purchase) and industrial (30% of purchase) paints. It is less used in automotive and furniture paints.

Titanium dioxide is the most widely used white pigment in the world. Only diamonds have more refraction indicators than titanium dioxide. Refraction indicator is called the measurement of the ability of light to bend. In this way, opacity and covering ability are provided. Only magnesium oxide is whiter than titanium dioxide. But the refractive indicator of this substance is much lower than titanium dioxide. This, in turn, means that much more magnesium oxide is required to achieve the desired dullness. Therefore, in practice, titanium dioxide is preferred.





Areas Of Use

  • In addition to its use as a food colorant, it is also used in the production of dyes and sun lotion.
  • It is widely used because it effectively distributes visible light, giving paints and coatings whiteness, brightness and opacity properties.
  • In the food sector, titanium dioxide is used in many products that are white, especially candy, chewing gum, baking powder, white chickpeas.
  • The most important function of titanium dioxide is that it provides brightness, whiteness and opacity in both paints and coatings, as well as in plastics, paper, ink, fiber, Pharmaceuticals (pills and tablets), food and cosmetics, provided that it is a pigment.
  • With this feature, titanium dioxide is used as a white color to coat the surface, to separate layers in products, and as a whitening agent in toothpaste.
  • Titanium dioxide is a mineral that is also used in cosmetics as a thickener, whitener, lubricant and a substance that reduces the sun's Rays.
  • It protects the skin from UVA and UVB radiation and there is no risk of skin irritation. The catalyst effect of light, i.e. the most common known use of photocatalysis, is the cleaning of environmental pollution. Thus, when light
