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.

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.
