Titanium Dioxide (TiO2)

What is Titanium Dioxide (TiO2)?

TiO2 (titanium dioxide) is an oxide of the metal titanium which occurs naturally as a rutile in some acid igneous rocks and metamorphic rocks, and is also in sedimentary rocks and beach sands. TiO2 (titanium dioxide) is found in heavy mineral sand deposits rutile and is often associated with a common titanium mineral, ilmenite, together with zircon, monazite and magnetite.

You will find TiO2in all kinds of paint, printing ink, plastics, paper, synthetic fibers, rubber, condensers, painting colors and crayons, ceramics, electronic components along with food and cosmetics.

Titanium Dioxide Uses

Titanium dioxide has many uses, including the following:

Pigment - 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. 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". In powder form 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.

Titanium dioxide is often used to whiten skimmed milk; this has been shown statistically to increase skimmed milk's palatability.

Titanium dioxide is used to mark the white lines on the tennis courts of the All England Lawn Tennis and Croquet Club.

Sunscreen and UV Absorber - In cosmetic and skin care products, titanium dioxide is used as a pigment, sunscreen and a thickener. It is also used as a tattoo pigment and in styptic pencils

Titanium Dioxide Photocatalyst - Many studies have been published on the use of TiO2 as a photocatalyst for the decomposition of organic compounds. TiO2 is active under UV light

Photocatalytic activity (PCA) is the ability of a material to create an electron hole pair as a result of exposure to ultraviolet radiation. The resulting free-radicals are very efficient oxidizers of organic matter. Photocatalytic activity in TiO2 has been extensively studied because of its potential use in sterilization, sanitation, and remediation applications. The ability to control PCA is important in many other applications utilizing TiO2 including paint pigments and cosmetics that require low PCA.

Titanium Dioxide Antimicrobial Coatings

The photocatalytic activity of titanium results in thin coatings of the material exhibiting self cleaning and disinfecting properties under exposure to UV radiation. These properties make the material a candidate for applications such as medical devices, food preparation surfaces, air conditioning filters, and sanitaryware surfaces.

Titanium Dioxide Air Purifiers

We carry one TiO2 air purifier technologies that utilize titanium dioxide. Most of the Surround Air Purifier models contain a TiO2-based filter.

Surround Air Multi-Tech Ionizers

Surround Multi-Tech Air IonizersNegative ions clean the air by magnetically attracting to pollutants until these newly-formed larger particles become too heavy to remain in the air you breathe and they fall to the ground. Surround Air Ionizers continually produce negative ions, without creating the "black-wall" effect of older ionization technologies, so even if one of these fallen particles is kicked up into the air, it is quickly removed again. The most important thing, though, is that they are taken out of the air, preventing you from inhaling them into your lungs, which is how they cause problems.

Since certain technologies are much better than others at removing different types of air pollutants, all Surround Ionizers are multi-technology. All models include ionization, a prefilter, a HEPA and Carbon Filter and UV lamp, plus some models include a TiO2 filter or an optional ozone sanitizer. And, the Intelli-Pro includes electronic sensors. With Surround, you get the best of the most advanced air purification technologies on the market, all rolled into one air purifier. The best part is that Surround Multi-tech ionizers and replacement filters are affordable for every budget. more info

Find the Right Air Purifier for
Your Unique Problem or Application

It's no mystery that the air inside our homes, offices and nearly every building we enter is contaminated with toxic air pollution problems. But wading through the plethora of air purification technologies and models to make our living and working space free of pollution can be a daunting task, especially with the misinformation presented by so many salespeople and web sites. There are many different air purification technologies and air filters on the market, but no one air purifier technology can solve every air pollution problem, which is why we carry different brands.
