of TiO2 (titanium dioxide)|
The element titanium is
finding more and more applications in today�s society. The use of
titanium metal in aerospace, sports and medicine is well known; in
fact, over 96% of the worldwide use of titanium is in the oxide
form, TiO2 (titanium dioxide), thus creating a high
The most important constituent of paint is titanium
dioxide, an opaque substance that gives paint its high gloss and
rich depth of color. TiO2 (titanium dioxide) replaced the dangerous
metal lead that was used in paint for this purpose. TiO2 (titanium
dioxide) has also been used for years in coloring for food and
cosmetics, crayons, and UV protection in sunscreens and many other
products we use every day.
The disinfectant and self-cleaning
qualities of TiO2 (titanium dioxide) are being widely employed in
Japan and many European countries today for such products as coated
ceramic tile for use in homes. This coating is reported to last the
life of the tile and is activated by a UV light source and water.
Other applications are TiO2 (titanium dioxide) coated self-cleaning
roof tiles for homes and buildings, which are also activated by the
UV light of the sun.
In addition, TiO2 (titanium dioxide) is
currently being used to treat the air in fruit, vegetable and cut
flower storage areas to prevent spoilage and increases the products�
shelf life. The photocatalytic properties of TiO2 (titanium dioxide)
remove ethylene gas from the air. Ethylene is a naturally occurring
gaseous hormone produced by plant tissue that in low concentrations
triggers the ripening of fruits and vegetables. Ethylene is also
produced from other sources including internal combustion engines,
certain fungi, and cigarette smoke.
These are just a few of
the products being developed today.
