Titanium dioxide can be extracted by acid decomposition of rutile or obtained
by decomposition of titanium tetrachloride. Titanium dioxide has stable
properties and is used in large quantities as a white pigment in paint. It has
good hiding power and is similar to lead white, but does not turn black like
lead white; it has the same durability as zinc white. Titanium dioxide is also
used as a matting agent for enamel, which can produce a very bright, hard and
acid-resistant enamel glaze.
Titanium Dioxide
Application field
Industrial application
Titanium dioxide is an important white pigment and porcelain glaze. Used in
paint, ink, plastic, rubber, paper, chemical fiber, watercolor paint and other
industries.
Use
Titanium dioxide is the whitest thing in the world. 1 gram of titanium
dioxide can paint an area of more than 450 square centimeters white. It is 5
times whiter than the commonly used white pigment-Lithopone, so it is the best
pigment for white paint. Titanium dioxide used as a pigment in the world can
reach hundreds of thousands of tons a year. Titanium dioxide can be added to
paper to make the paper white and opaque. The effect is 10 times greater than
other materials. Therefore, it is necessary to add titanium dioxide to banknote
paper and art paper.
In order to lighten the color of plastic and soften the luster of rayon,
titanium dioxide is sometimes added.
In the rubber industry, titanium dioxide is also used as a filler for white
rubber.
The photochemical properties of semiconductor titanium dioxide have made it
useful in many fields, such as the purification of air, water and fluids.
Photocatalysts doped with carbon or other heteroatoms can also be used in sealed
spaces or areas with scattering light sources. When used in coatings on
buildings, pedestrian slabs, concrete walls or roof tiles, they can
significantly increase the decomposition of air pollutants such as nitrogen
oxides, aromatics and aldehydes.
In addition, it is widely used in the production of sunscreen, which is
non-toxic and harmless to the human body.
Ultrafine titanium dioxide has excellent UV light shielding and transparency.
It is widely used in cosmetics, wood protection, food packaging plastics,
durable household films, man-made fibers and natural fibers, and transparent
coatings. The special optical effect in metallic flash coating makes it pay
attention to and applied in high-end car paint.
