The Effect of Different Outer Cations on the Stability of Fluorotitanium Complex

Fluoride-rich fluid is believed to be able activate and migrate Ti other high field-strength elements the greatest extent. The stability of F-rich titanium complexes can ensure their migration in fluid, but inseparable from physical chemical properties such as concentration, temperature pH value—important factors affecting complexes. In this study, influence outer cationic complex on fluorine was studied. Studies were based different kinds (K2TiF6, Na2TiF6, (NH4)2TiF6 H2TiF6) 100 MPa pressure. Under condition 200~500 °C temperature, we found that rises, hydrolysis violent. We compared four F-titanium with cations according rate cumulative equilibrium constant. alkali metal are more stable, K2TiF6 Na2TiF6. However, an acidic relatively unstable, which not conducive elements. Due water–rock reactions occur hydrothermal migration, mixing alteration, once system, composition, value change. Thus, becomes extremely leading precipitation growth Ti-rich minerals.
