专利摘要:
Metals and metalloids are produced by cathodically dissolving their compounds in electrolytic cells, which comprise one or more heterogeneous bipolar electrodes in series, with terminal electrodes as cathodes and other terminal electrodes as soluble or inert anodes. The compounds are introduced into the cells and brought in contact with the cathodic sides of the heterogeneous bipolar electrodes. The cathodic half-reaction permits the reduction and the dissolution of the compounds, while terminal negative electrodes may hostthe electrolytic deposition of the metals. The cells may also comprise an electrowinning system of anodes and cathodes for depositing the dissolved metals.

The invention relates to an electrically conducting bipolar electrode using
metallurgy of titanium, lead and silicon and can be used to obtain these elements from their compounds by electrolysis in melts
The purpose of the invention is to increase the productivity of the process.
Example 1. Electrolytic
The production of titanium from its tetrachloride Q over silicon is 2.3 kg / hr, with a bipolar silicon dioxide feed rate of the type using a bipolar electrode of lead as the cathode part. The process is conducted in an electrolyte containing,%: sodium chloride 69.9, | 5 lead chloride 4.1, titanium chlorides 26 with an average valence of titanium in them 2.05. Electrolyte temperature
