    摘要: A mixed molten salt containing CaCl2 and NaCl is held in the reactor cell 1 at a temperature not more than 600° C. TiCl4 which is of a Ti raw material is introduced into the reactor cell 1 while Na is introduced into the reactor cell 1. Na introduced into the reactor cell 1 is replaced by Ca, Ca is dissolved in the molten salt, Ca reduces TiCl4 introduced into the reactor cell 1, and thereby Ti particles are generated. The generated Ti particles are introduced to a separation cell 2 along with the molten salt, and the Ti particles and Na are separated from the molten salt. The residual molten salt is introduced to an electrolytic cell 3 to generate Na by high-temperature electrolysis at the temperature more than 600° C. The generated Na is returned to the reactor cell 1 to replenish Na consumed in the reactor cell 1. The highly reactive Ca is not directly handled, and Na which is easy to handle is used in a circulating manner. Therefore, the Ti or Ti alloy can economically be produced by Ca reduction.

    摘要: A purification method of a metal salt which comprises bringing a metal salt formed by melting an alkali metal salt, an alkaline earth metal salt or a mixture thereof into contact with titanium or the like, thereby adsorbing impurities in the metal salt, a deoxidization method by melting metallic calcium into a molten product of the metal salt purified by the purification method and bringing the same into contact with a titanium material, and a production method of the titanium material which comprises conducting molten salt electrolysis by using the molten product of the purified metal salt for an electrolytic bath. Using the purification or production method the molten metal salt can be purified simply and conveniently at good efficiency. Then, use of the purified metal salt can minimize contamination caused by the metal impurities in the molten salt and the titanium material of high quality can be produced.

    摘要: An electrolytic cell for reducing a metal oxide, such as titania, in a solid state is disclosed. The electrolytic cell includes an anode formed from carbon and a cathode formed at least in part from the metal oxide. The electrolytic cell also includes a membrane that is permeable to oxygen anions and is impermeable to carbon in ionic and non-ionic forms positioned between the cathode and the anode to thereby prevent migration of carbon to the cathode.

    摘要: Metals and metalloids are produced by cathodically dissolving compounds thereof in electrolytic cells. These cells have one or more heterogenous bipolar electrodes in series, with a terminal electrode as cathode and another terminal electrode as a soluble or inert anode. A common electrolyte is in contact with all electrodes.The compounds of the metals or metalloids are introduced into the cells and are brought into contact with the cathodic sides of the heterogenous electrodes. A cathodic half reaction takes place on the heterogenous bipolar electrode which permits the reduction and dissolution of the metal and metalloid compounds into the common electrolyte. The terminal negative electrodes are the site of the electrolytic deposition of the metals.The cells may also include an electrowinning system of anodes and cathodes, connected by way of the common electrolyte, for depositing the dissolved metals.
