Titanium Dioxide

Titanium dioxide,also known as titanium(IV) oxide or titania,is the naturally occurring oxide of titanium,chemical formula TiO 2. When used as a pigment,it is called titanium white, Pigment White 6(PW6), or CI 77891.Generally, it is sourced from ilmenite, rutile and anatase. It has a wide range of applications, including paint, sunscreen and food coloring. When used as a food coloring, it has E number E171. World production in 2014 exceeded 9 million metric tons. It has been estimated that titanium dioxide is used in two-thirds of all pigments, and pigments based on the oxide have been valued at $13.2 billion.vert to rutile upon heating.
