Titanium dioxide (TiO 2) has been called “the environmental white knight” because it is not considered obvious toxic, is very functional, and can be used for numerous coatings (Park et al., 2006). Titanium dioxide (NPs) is photocatalytic – that is, it becomes catalytic when exposed to ultraviolet (UV) light.
Titanium dioxide is a white metal oxide used in many food categories as food additives to provide a whitening effect. If its use complies with the five specifications including synthesis pathway, crystallographic phase, purity, amount and innocuousness, all other parameters are not defined and were hardly documented.

Titanium dioxide is a naturally occurring chemical that has a white powdery appearance and is formed by the reaction of oxygen and titanium. The chemical formula for titanium dioxide is TiO 2.It provides a high level of corrosion resistance on titanium surfaces due to the ease of passivation in oxidized environments where it forms a protective oxide film.
We are into offering Titanium Dioxide (Anatase) Shankh Brand that is a brilliant white, non-toxic pigment. The unique properties of Titanium Dioxide (Anatase) which makes it supreme among the white pigments are its excellent opacity, extreme whiteness, and chemical stability, which lead to considerable economy in usage.
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.
Rutile has a tetragonal unit cell, with unit cell parameters a = b = 4.584 Å, and c = 2.953 Å. The titanium cations have a coordination number of 6, meaning they are surrounded by an octahedron of 6 oxygen atoms. The oxygen anions have a coordination number of 3, resulting in a trigonal planar coordination.

Aug 28, 2013· Abstract. This paper presents the results of the measurements and analysis of the influence of laser process parameters on the color obtained. The study was conducted for titanium (Grade 2) using a commercially available industrial pulsed fiber laser.
Titanium falls into a family of metals called reactive metals, which means that they have a strong affinity for oxygen. At room temperature, titanium reacts with oxygen to form titanium dioxide. This passive, impervious coating resists further interaction with the surrounding atmosphere, and it gives titanium its famous corrosion resistance.
Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium, chemical formula TiO2.When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891.
