Titanium Dioxide (TiO2) Powder (Rutile Grade) General Description:
a) Titanium dioxide is available in two primary classes according to the three structures of anatase, rutile and fumed.
b) Rutile is a mineral composed primarily of titanium dioxide, TiO2.
c) Rutile is the most common natural form of TiO2.
d) Rutile has among the highest refractive indices of any known mineral and also exhibits high dispersion. Natural rutile may contain up to 10% iron and significant amounts of niobium and tantalum.
e) Rutile derives its name from the Latin rutilus, red, in reference to the deep red color observed in some specimens when viewed by transmitted light.

Titanium Dioxide (TiO2) Powder (Rutile Grade) Typical Applications:
a) Paint pigment, opacifying agent, welding rod fluxes, optical coatings, as a catalyst, ceramic finish coat, plastics, elastomers, coated fabrics, printing inks, roofing granules, glass, and in glazes.
b) Finely powdered rutile is a brilliant white pigment and is used in paints, plastics, paper, foods, and other applications that call for a bright white color. Titanium dioxide pigment is the single greatest use of titanium worldwide.
c) Nanoscale particles of rutile are transparent to visible light but are highly effective in the absorption of ultraviolet radiation. The UV absorption of nano-sized rutile particles is blue-shifted compared to bulk rutile, so that higher energy UV light is absorbed by the nanoparticles. Hence, they are used in sunscreens to protect against UV induced skin damage.
d) Small rutile needles present in gems are responsible for an optical phenomenon known as asterism. Asterated gems are known as "star" gems. Star sapphires, star rubies, and other "star" gems are highly sought after and often more valuable than their normal equivalents.

Titanium Dioxide (TiO2) Powder (Rutile Grade) TSCA (SARA Title III) Status:
a) Listed. For further information please call the U.S. Environmental Protection Agency at +1.202.554.1404
b) Titanium dioxide is incompatible with strong oxidizers and strong acids. Violent or incandescent reactions may occur with metals (e.g. aluminium, calcium, magnesium, potassium, sodium, zinc and lithium).
c) Titanium dioxide dust, when inhaled, has recently been classified by the International Agency for Research on Cancer (IARC) as an IARC Group 2B carcinogen possibly carcinogenic to humans.
