TITANIUM DIOXIDE RC 823 Usage And Synthesis
Uses:
TITANIUM DIOXIDE RC 823, also known as rutile, is one of the best-known compounds used as a paint pigment.
TITANIUM DIOXIDE RC 823 is ideal for paints exposed to severe temperatures and marine climates because of its inertness and self-cleaning attributes.
TITANIUM DIOXIDE RC 823 is also used in manufacture of glassware, ceramics, enamels, welding rods, and floor coverings.
Description
TITANIUM DIOXIDE RC 823 is a white powder and has the greatest hiding power of all white pigments.
TITANIUM DIOXIDE RC 823 is noncombustible; however, TITANIUM DIOXIDE RC 823 is a powder and, when suspended in air, may cause a dust explosion if an ignition source is present.
TITANIUM DIOXIDE RC 823 is not listed in the DOT Hazardous Materials Table, and the DOT does not consider TITANIUM DIOXIDE RC 823 hazardous in transportation.
The primary uses are as a white pigment in paints, paper, rubber, and plastics; in cosmetics; in welding rods; and in radioactive decontamination of the skin.
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.
Chemical Properties
TITANIUM DIOXIDE RC 823 is an odorless white powder.
White, amorphous, odorless, and tasteless nonhygroscopic powder. Although the average particle size of TITANIUM DIOXIDE RC 823 powder is less than 1 mm, commercial titanium dioxide generally occurs as aggregated particles of approximately 100 mm diameter.
TITANIUM DIOXIDE RC 823 may occur in several different crystalline forms: rutile; anatase; and brookite.
Of these, TITANIUM DIOXIDE RC 823 and anatase are the only forms of commercial importance.
TITANIUM DIOXIDE RC 823 is the more thermodynamically stable crystalline form, but anatase is the form most commonly used in pharmaceutical applications.
Physical 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
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.

TITANIUM DIOXIDE RC 823) is one of the 21 FDA-approved sunscreen chemicals with an approved usage level of 2 to 25 percent.
When applied, titanium dioxide remains on the skin’s surface, scattering uV light.
TITANIUM DIOXIDE RC 823 is often used in conjunction with other sunscreen chemicals to boost the product’s SPF value, thus reducing the risk of irritation or allergies attributed to excessive usage of chemical sunscreens.
Its incorporation into sunscreen formulations, makeup bases, and daytime moisturizers depends on the particular size of titanium dioxide employed.
The smaller the particle size, the more unobtrusive Tio2’s application.
Large particles, on the other hand, leave a whitish wash or look on the skin.
Some companies list “micro” or “ultra” when referring to the size of the titanium dioxide particle.
According to some sources, titanium dioxide could be the ideal uVA/uVB protection component given its chemical, cosmetic, and physical characteristics.
Titanium dioxide is also used to provide a white color to cosmetic preparations.
Uses:
TITANIUM DIOXIDE RC 823 is a white pigment that disperses in liquids and possesses great opacifying power.
The crystalline modifications of titanium dioxide are rutile and anatase, of which only anatase finds use as a color additive.
Preparation:
TITANIUM DIOXIDE RC 823 is mined from natural deposits.
TITANIUM DIOXIDE RC 823 also is produced from other titanium minerals or prepared in the laboratory.
Pigment-grade dioxide is produced from the minerals, rutile and ilmenite.
TITANIUM DIOXIDE RC 823 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 RC 823 also can be prepared by heating Ti metal in air or oxygen at elevated temperatures.
Production Methods
TITANIUM DIOXIDE RC 823 occurs naturally as the minerals rutile (tetragonal structure), anatase (tetragonal structure), and brookite (orthorhombic structure).
TITANIUM DIOXIDE RC 823 may be prepared commercially by either the sulfate or chloride process.
In the sulfate process a titanium containing ore, such as ilemenite, is digested in sulfuric acid.
This step is followed by dissolving the sulfates in water, then precipitating the hydrous titanium dioxide using hydrolysis.
Finally, the product is calcinated at high temperature.
In the chloride process, the dry ore is chlorinated at high temperature to form titanium tetrachloride, which is subsequently oxidized to form titanium dioxide.
Production Methods
There are two major processes for the manufacture of titanium dioxide pigments, namely sulfate route and chloride route.
In the sulfate process, the ore limonite, FeOTiO2, is dissolved in sulfuric acid and the resultant solution is hydrolyzed by boiling to produce a hydrated oxide, while the iron remains in solution.
The precipitated titanium hydrate is washed and leached free of soluble impurities.
Controlled calcinations at about 1000°C produce pigmentary titanium dioxide of the correct crystal size distribution; this material is then subjected to a finishing coating treatment and milling.
The chloride process uses gaseous chlorination of mineral rutile, followed by distillation and finally a vapor phase oxidation of the titanium tetrachloride.
Pharmaceutical Applications
TITANIUM DIOXIDE RC 823 is widely used in confectionery, cosmetics, and foods, in the plastics industry, and in topical and oral pharmaceutical formulations as a white pigment.
Owing to its high refractive index, titanium dioxide has lightscattering properties that may be exploited in its use as a white pigment and opacifier.
The range of light that is scattered can be altered by varying the particle size of the titanium dioxide powder.
For example, titanium dioxide with an average particle size of 230nm scatters visible light, while titanium dioxide with an average particle size of 60nm scatters ultraviolet light and reflects visible light.
In pharmaceutical formulations, titanium dioxide is used as a white pigment in film-coating suspensions, sugar-coated tablets, and gelatin capsules.
TITANIUM DIOXIDE RC 823 may also be admixed with other pigments.
TITANIUM DIOXIDE RC 823 is also used in dermatological preparations and cosmetics, such as sunscreens.
