“…The calculated theoretical density and Ti-X distances are 3.114 Mg m À3 and 1.911 Å , respectively. This hexagonal TiOF 2 structure is closely related to the previously reported cubic ReO 3 -type structure of TiOF 2 (Vorres & Donohue, 1955;Hayward et al, 2005;ICDD, 2007). The cubic TiOF 2 structure (space group Pm3m), illustrated in Figs.…”

“…In 1955, Vorres & Donohue evaluated the crystal structure of titanium oxyfluoride generated by the hydrolysis of titanium tetrafluoride (TiF 4 ) or titanium trifluorochloride (TiF 3 Cl), or by the reaction of hydrogen fluoride with titanium dioxide (Vorres & Dutton, 1955). The room temperature X-ray powder diffraction pattern of TiOF 2 was found to be consistent with a simple cubic crystal structure (Vorres & Donohue, 1955). More recently, gas/solid metathetic reactions of the following type have been suggested for converting silica structures into replicas composed of other materials (Sandhage et al, 2002;Sandhage, 2006): 2TiF 4 ðgÞ þ SiO 2 ðsÞ !…”

“…30 These authors successfully synthesized this compound using two different routes: hydrolysis of titanium tetrafluoride or titanium trifluorochloride or reaction of aqueous or anhydrous HF with TiO 2 . The oxyfluoride crystallizes in the Pm-3m space group with a lattice parameter of 3.80 Å , and a powder density of 3.06 g.cm À3 with one TiOF 2 molecule per unit cell.…”

“…The first-reported titanium oxyfluoride, TiOF 2 , was synthesized and characterized in 1955 by Vorres and Donohue. 30 Focussing on this, in 2006, Reddy et al 31 investigated the electrochemical behaviour of TiOF 2 with Li metal under discharge-charge conditions. Topotactic Li reactions with other ReO 3 -type compounds have been investigated.…”

Properties and applications of technologically important inorganic compounds of titanium are surveyed. The most important compound is titanium dioxide which, because of its high refractive index, is manufactured as a white pigment at a scale of ca 7 million tpa. Raw materials and pigment production processes are reviewed. Mixed oxides, for example, barium titanate, are important raw materials for electroceramics. Titanium hydrides provide a convenient method of hydrogen storage. Titanium boride, titanium carbide, and titanium nitride are used as components of hard materials, for example, for cutting tools. They are electrically conducting. The chlorides are the most important halides. Titanium trichloride is the basis of widely used polymerization catalysts. Titanium tetrachloride is an intermediate in the production of both titanium metal and (via the chloride process) titanium dioxide pigment. Titanium dioxide pigment is also made (in the sulfate process) by precipitation from solutions of titanium in sulfuric acid. Titanium sulfides may be used as cathodes in high efficiency batteries. The properties of some titanium compounds with silicon and phosphorus are reviewed. Analytical methods and environmental, health and safety aspects are summarized.
