Titanium (III) fluoride is a chemical compound of titanium from the group of fluorides .

Extraction and presentation

Titanium (III) fluoride can be obtained by reacting titanium (III) oxide or hydroxide and hydrofluoric acid.

properties

Titanium (III) fluoride forms deep blue crystals, reacts with water and easily hydrolyzes to form hydrofluoric acid. From 950 ° C it begins to disproportionate to titanium (IV) fluoride and titanium . It crystallizes trigonally in the space group R 3 c (space group no. 167) with the lattice parameters a = 5.43 and c = 13.64 Å ( vanadium (III) fluoride structure ). Template: room group / 167

use

Titanium (III) fluoride can be used to manufacture catalysts based on silicic acids .
