TiO2 Overview

Based on proven Titanium-dioxide (TiO2), XTI has developed world-exclusive methods to maximize all the known benefits and corrected the weaknesses of such a widely used and time-proven technology, elevating TiO2 to a new level that can deliver near 100% efficiency in real-world applications and to be applicable onto many different types of surfaces previously not possible. To learn about XTI Nano Particle Technology, one can start by understanding TiO2 (photocatalyst), for which there is vast published information and resources available online, enclosed is a summary:

TiO2 General Information

(Wikipedia - http://en.wikipedia.org/wiki/Tio2) Titanium dioxide (TiO2), also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium, chemical formula TiO2. When used as a pigment, it is called titanium white, Pigment White 6, or CI 77891. It is noteworthy for its wide range of applications, from paint to sunscreen to food colouring, for which it was given E number E171.


Titanium dioxide is the most widely used white pigment because of its brightness and very high refractive index (n = 2.7), in which it is surpassed only by a few other materials. Approximately 4 million tons of pigmentary TiO2 are consumed annually worldwide. When deposited as a thin film, its refractive index and color make it an excellent reflective optical coating for dielectric mirrors and some gemstones like "mystic fire topaz". TiO2 is also an effective opacifier in powder form, where it is employed as a pigment to provide whiteness and opacity to products such as paints, coatings, plastics, papers, inks, foods, medicines (i.e. pills and tablets) as well as most toothpastes. Opacity is improved by optimal sizing of the titanium dioxide particles.

Used as a white food coloring, it has E number E171. Titanium dioxide is often used to whiten skimmed milk; this has been shown statistically to increase skimmed milk's palatability.

In cosmetic and skin care products, titanium dioxide is used both as a pigment and a thickener. It is also used as a tattoo pigment and in styptic pencils.

This pigment is used extensively in plastics and other applications for its UV resistant properties where it acts as a UV absorber, efficiently transforming destructive UV light energy into heat.

In ceramic glazes titanium dioxide acts as an opacifier and seeds crystal formation.
