Titanium dioxide Chemical Properties,Uses,Production

Chemical Properties

white to almost white powder

Chemical Properties

The naturally occurring dioxide exists in three crystal forms: anatase, rutile and brookite. While rutile, the most common form, has an octahedral structure. Anatase and brookite have very distorted octahedra of oxygen atoms surrounding each titanium atom. In such distorted octahedral structures, two oxygen atoms are relatively closer to titanium than the other four oxygen atoms. Anatase is more stable than the rutile form by about 8 to 12 kJ/mol (Cotton, F.A., Wilkinson, G., Murillo, C.A and M Bochmann. 1999. Advanced Inorganic Chemistry, 6th ed, p. 697, New York: John Wiley & Sons) Other physical properties are: density 4.23g/cm3; Mohs hardness 5.8 g/cm3 ( anatase and brookite) and 6.2 g/cm3 ( rutile); index of refraction 2.488 (anatase), 2.583 (brookite) and 2.609 (rutile); melts at 1,843°C; insoluble in water and dilute acids; soluble in concentrated acids.

Uses

Titanium dioxide is an extreme white and bright compound with high index of refraction. In paints it is a white pigment and an opacifying agent.It is in house paints, water paints, lacquers, enamels, paper filling and coating, rubber, plastics, printing ink, synthetic fabrics, floor coverings, and shoe whiteners. Also, it is used in colorants for ceramics and coatings for welding rods. A rutile form of the dioxide is used in synthetic gem stones.

Uses

Industry Application Role/benefit
Pigment Optical coating for dielectric mirrors and gemstones Brightness and very high refractive index
Paper coating Helps to make paper whiter, brighter and more opaque
Plastics, adhesives and rubber Helps minimize the brittleness, fading and cracking that can occur as a result of light exposure
Food Contact materials and ingredients Prevents premature degradation and enhance the longevity of the product
Paints Gives paint its high gloss and rich depth of color
Ceramic glazes Acts as an opacifier and seeds crystal formation
Cosmetic Sunscreens Active ingredients/high refractive index and strong UV light absorbing capabilities
Daily cosmetics or make-up materials Additive/aids in hiding blemishes and brightening the skin
Toothpastes Additive/helps to whiten tooth
Catalyst Dye-sensitized solar cell Can produce electricity in nanoparticle form
Hydrolysis reaction Catalyzes the photo decomposition of water into hydrogen and oxygen
Automotive, power stations, etc. Helps to removes harmful exhaust gas emissions, such as nitrous oxides, volatile organic compounds, etc.
Detoxification or remediation of wastewater Photocatalytically mineralizes pollutants (to convert into CO2 and H2O) in waste water
Photocatalytic antimicrobial coating Photocatalytic destruction of organic matter
Others Oxygen sensor The electrical resistivity of TiO2 can be correlated to the oxygen content of the atmosphere
Anti-fogging coatings and self-cleaning windows Under exposure to UV light, TiO2 becomes increasingly hydrophilic
Coated ceramic tile Disinfectant and self-cleaning qualities
Treatment of the air in fruit, vegetable and cut flower storage areas Removes ethylene gas to prevent spoilage and prevents internal combustion
Memristor Can be employed for solar energy conversion
Mixed conductor Significant ionic and electronic conduction
 
   

Preparation

Titanium dioxide is mined from natural deposits. It also is produced from other titanium minerals or prepared in the laboratory. Pigment-grade dioxide is produced from the minerals, rutile and ilmenite. Rutile is converted to pigment grade rutile by chlorination to give titanium tetrachloride, TiCl4. Anhydrous tetrachloride is converted back to purified rutile form by vapor phase oxidation.
Anatase form is obtained by hydrolytic precipitation of titanium(IV) sulfate on heating. The mineral ilmenite is treated with concentrated sulfuric acid. Heating the sulfate solution precipitates hydrous titanium oxide. The precipitate is calcined to expel all water.
Titanium dioxide also can be prepared by heating Ti metal in air or oxygen at elevated temperatures.
