Pure Tung Oil, TiO2, is a white powder and has the greatest hiding power of all white pigments. 
Pure Tung Oil is noncombustible; however, it is a powder and, when suspended in air, may cause a dust explosion if an ignition source is present. 
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.

Pure Tung Oil is a natural, non-toxic drying oil extracted from the seeds of the tung tree (Vernicia fordii), a plant native to China and parts of Southeast Asia. 
Known for its excellent penetrating and protective properties, pure tung oil has been used for centuries in woodworking, construction, and artistic applications. 
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. 

White, amorphous, odorless, and tasteless nonhygroscopic powder. 
Although the average particle size of Pure Tung Oil powder is less than 1 mm, commercial titanium dioxide generally occurs as aggregated particles of approximately 100 mm diameter.
Pure Tung Oil may occur in several different crystalline forms: rutile; anatase; and brookite. 
Of these, rutile and anatase are the only forms of commercial importance. 

Rutile is the more thermodynamically stable crystalline form, but anatase is the form most commonly used in pharmaceutical applications.
Metastable over long periods of time despite being less thermodynamically stable than rutile. 
However, above 700°C, the irreversible and rapid monotropic conversion of anatase to rutile occurs. 

Pure Tung Oil exhibits a greater transparency in the near-UV than rutile. 
With an absorption edge at 385 nm, anatase absorbs less light at the blue end of the visible spectrum and has a blue tone.
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.

Pure Tung Oil occurs in nature in the crystalline forms rutile, anatase, and brookite. 
Rutile and anatase are manufactured in large quantities, which are primarily used as pigments, but also as catalysts and in ceramics.
Pure Tung Oil is of outstanding importance as a white pigment because of its scattering properties, its chemical stability, its biological inertness, and its lack of toxicity.

The pigment is frequently coated with colorless organic or inorganic compounds of low solubility to improve its weather resistance, lightfastness, and dispersibility.
Pure Tung Oil occurs naturally as the minerals rutile (tetragonal structure), anatase (tetragonal structure), and brookite (orthorhombic structure).
Pure Tung Oil 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 Pure Tung Oil using hydrolysis. 
Finally, the product is calcinated at high temperature. 

In the chloride process, the dry ore is chlorinated at high temperature to form Pure Tung Oil, which is subsequently oxidized to form titanium dioxide.
There are two major processes for the manufacture of Pure Tung Oil 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 Pure Tung Oil is washed and leached free of soluble impurities. 
Controlled calcinations at about 1000°C produce pigmentary Pure Tung Oil of the correct crystal size distribution; this material is then subjected to a finishing coating treatment and milling.

Lignea, the oil obtained from the fruits of the tung tree, has many uses both indoors and out, e.g. for indoor and outdoor furniture, decks, flooring, turned items, musical instruments, wooden toys and wooden boats and can be used for impregnating fabrics and even masonry. 

Pure Tung Oil is absorbed by wooden surfaces very quickly and hardens them after it has dried, making them mechanically stronger and highly water-resistant. 
It provides approximately twice as much protection as linseed oil. 
It deepens colours and enhances the contrast of the grain, but the wood retains its natural visual and tactile characteristics. 

The protective film is elastic, even in the long term, and, in contrast to linseed oil, darkens very little. 
The surfaces can be refreshed or repaired by applying a new coat. Lignea can be applied without any problems, even in multiple coats, using either a brush or a piece of cloth, and can be thinned with turpentine or mixed with other vegetable oils (e.g. linseed or camellia oil) depending on the user’s preference.
