Titanium dioxide, aka TiO2, is a fine white
powder that provides extreme whiteness to materials such as paints, plastics,
papers, inks and so on. The paints containing TiO2 have high hiding power, also
known as the ability to hide a substrate. Titanium dioxide can make this more
effectively than any other white pigment being used in paints. Since titanium
dioxide has very high opacity and whiteness, the TiO2 white pigment is the most
important material used by the paints and plastics industry to add extra
whiteness and opacity to the products. These unique properties of titanium
dioxide are all derived from its refractive index which expresses the ability
to bend and scatter light. As far as we know, titanium dioxide has the highest
refractive index of any material, even diamond.
Titanium dioxide is widely used as an
opacifier in glass and porcelain enamels, paints, paper, plastics, cosmetics,
sunscreens and other industries. Before being used in these products, titanium
dioxide needs to be mined, refined and ground to a fine, uniform particle size.
One of the most important advantages that titanium dioxide has is its
resistance to discoloration under UV light. Titanium dioxide is found in a form
known as ilmenite which is found in the iron ore.
In conclusion, there are three major
applications of titanium dioxide. First, titanium dioxide can be used as a
pigment. Tio2 used to give whiteness and opacity to products such as paint,
plastics, paper, inks, fibers, food and cosmetics. Second, titanium dioxide can
be used as anti microbial coating. The titania in tio2 has photo catalytic
property which makes the material an option for applications such as food preparation
surfaces, medical devices, air conditioning purifiers and sanitary ware
surfaces. Last, titanium dioxide can be used as oxygen sensors. Titanium
dioxide can be used to sense the amount of oxygen present in an atmosphere
which is used for studying the contents of atmosphere. For more information
