To produce the rutile titanium dioxide pigment, hydrolysis of the mother liquor has to be carried out in the presence of a specially prepared hydrosol as a seeding agent. This hydrosol is made by the neutralization of a portion of the mother liquor in the presence of hydrochloric or some other monohydric acid. Because of the large amount of the hydrosol that must be added to the mixture (about 6% concentration), the hydrolysis reaction takes only about 1 hr. 

The chief mined ore of titanium is ilmenite (iron titanium oxide, FeTiC>3) and it occurs as vast deposits of sand in Western Australia, Canada and the Ukraine. Large deposits of rutile (titanium dioxide, TiO ) are known in North America, and South Africa. World production of the metal itself is around 90,000 tonnes per year, small compared to titanium dioxide production which is 4.3 million tonnes per year. Reserves of titanium amount to more than 600 million tonnes and while there is an abundance of this element it is extremely costly because it has to be extracted by a complicated process, and yet it could be so much more useful if it was cheaply available.

All rutile pigments are derived from the rutile titanium dioxide structure. Rutile forms of complex inorganic pigments are by far the most commonly used in plastics. The following are among the most widely used ... 

This was the basis of the approach by Chessick et al. (1954, 1955) and Zettlemoyer etal. (1958), which involved the use of a series of immersion liquids such as butyl derivatives differing only in their polar groups 1-butanol, 2-butanol, butanal, 1-aminobutane, 1-chlorobutane, butanoic acid. With the polar surfaces studied (rutile, CaF2, Aerosil, alumina), an approximately linear relation was found between the energy of immersion and the dipole moment. The slope gave directly the average field strength (for instance, 820 V//rm 1 on a rutile titanium (tv) oxide) and the... 

In the chloride process, the titanium-containing raw materials ilmenite, leucoxene, rutile, titanium slag, or anatase are chlorinated at 700-1200 °C. The TiCU is oxidized at temperatures of900-1400 °C to form Ti02. This raw pigment is ground and coated with inorganic compounds. 

Dukhin and Goetz [253] found a non-linear attenuation spectra for rutile titanium dioxide dispersions in the volume concentration range 1% to 42% and developed a theory to account for this. Dukhin et al. [254] state that viscous losses are dominant in high density contrast dispersions e.g. rutile whereas thermal losses are dominant in low-density contrast dispersions e.g. latices. A report of two years experience of operating this instrument was reported by Hinze et.al. [255].

The surfaces of mtile Ti02 have been the subject of intense research because of their photo-catalytic properties for the dissociation of water. The hydroxylation rate on the surface and the kinetics of the reaction were shown to depend strongly on the surface stoichiometry and detailed atomic structure. In addition, like the two above surfaces of sapphire and magnesium oxide, rutile titanium dioxide surfaces stand as model metal oxide surfaces. Their atomic structure is thus of fundamental interest.

The starting materials for Ti02 production are ilmenite and titanium slag in the case of the sulfate process (see Section 5.9.2.2.3) and leucoxene, rutile, synthetic rutile, titanium slag and in the future possibly also anatase for the chloride process (see Section 5.9.2.2.3). 

Dimensionally stable anodes (DSAs) made of a corrosion-resistant titanium screening have been adopted by both mercury cell and diaphragm cell operators. A baked-on rutile titanium dioxide paste used with these electrodes decreases the electrochemical overvoltage and raises practical operating current densities. While significantly more expensive than graphite, this anode...
