Preparation of Titanium by Fluoride Electrolysis

Abstract

Preparation of commercially pure titanium metal powder by electrolysis of K:~TiF~ in molten NaCI is described. The process is carried out under an inert atmosphere in an all-graphite cell. Operating conditions of the electrolysis and their effect upon the metal so produced are discussed. Preparation of the K2TiF~ and the electrolytic procedure are completely described. The process is capable of producing metal of high purity which may be consolidated and fabricated by standard techniques as applied to metal powders. The metal is recovered by aqueous washing techniques. It may be prepared either as coarsely crystalline metal or as coarse thin metal flakes.

Electrochemical Behavior of Ti(III) Ions in Molten LiF–LiCl: Comparison with the Behavior in Molten KF–KCl

“…Previous reports have shown that metallic titanium can be electrodeposited only from high-temperature molten salts as electrolytes. Generally, chlorides, [1][2][3][4][5][6][7][8][9][10][11][12][13] fluorides, [14][15][16][17][18] and chloride-fluoride mixtures [19][20][21][22][23][24][25][26][27][28][29][30][31] have been used as the molten salt electrolytes for titanium electrodeposition. The morphology of the Ti deposits closely depends on the type of salts used as electrolyte.…”

Electrochemical Behavior of Titanium Complexes in the KCl-KF Melt with Additions of Alkaline Earth Metal Cations

“…The solution was passed through a hot filter and cooled. The resulting potassium hexafluorotitanate crystals were dried in a vacuum, first at 363 K for 24 h and then at 423 K for 6 h. 26 Barium chloride (chemical pure) was dried in a vacuum oven at 433 K for 24 h. Barium fluoride (analytically pure grade), magnesium fluoride (high purity) and calcium chloride (pure grade) were used without additional processing.…”

Study of the Electron Transfer in Titanium Containing Melts by Electrochemical and Quantum-Chemical Methods

“…The solution was passed through a hot filter and was evaporated. The resulting K 2 TiF 6 crystals were dried in a vacuum, first at 363 K for 24 h and then at 423 K for 6 h. 35 Calcium chloride (Sigma Aldrich 99.0% min.) was dehydrated in vacuum at 413 K for 2 h. 36 The (NaCl-KCl) equimol -NaF (10 wt%) electrolyte was placed into a glassy carbon crucible, loaded into a retort of the electrochemical cell, the above-described vacuum-melting operations were repeated, then K 2 TiF 6 and CaCl 2 were introduced into the melt.…”
