    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: A new process or method has been developed whereby the purity of metal halides, prepared by conventional methods, can be significantly upgraded. The process, which includes a scrubbing of metal halides with a halide-source species in the vapor phase, has been shown to be effective not only in reducing the concentration of oxyanion impurities and volatile cation halide impurities, but effective in reducing hydroxyl ion (OH.sup.-) contaminations as well.Metal halides purified by this method are particularly useful as starting materials for growing optically pure metal halide crystals.

    摘要: This document describes a method for reducing the corrosivity of certain magnesium salts. The salt product resulting from the method exhibits reduced corrosion of steels that come into contact with the salt relative to salt compositions that are not so treated. This makes such treated salts more efficient coolant salts as they will require less equipment replacement over time. The method uses magnesium metal to reduce unwanted impurities in the salts the reduced impurities are then removed as either gas or precipitate from the now purified salt. Without being bound to one particular theory, it is believed that the reduction of the level of impurities in the salt results in a salt with substantially reduced corrosiveness to steel.

    摘要: Substantially anhydrous magnesium chloride is prepared through the chlorination of a hydrated magnesium chloride by melting the hydrated chloride, feeding that molten material to a bed of carbonaceous material so that it flows downwardly therethrough and simultaneously feeding a mixture of chlorine and air to the bed of carbonaceous material so that it flows upwardly therethrough countercurrent to the molten material, until magnesium chloride of the desired state of purity is obtained, and the purified magnesium chloride is then recovered.

    摘要: A process is described for recovering alkali-chloride and alkali-sulfate salts from a salt solution. The salt solution comprises alkali metal, chloride and sulfate ions and is directed to a hydrous salt crystallization unit which crystallizes hydrated sulfate salts that comprise sulfate and at least one alkali metal. A purged solution from the hydrous salt crystallization unit is directed to a chloride salt crystallization unit while the hydrated sulfate salt crystals are melted to form an aqueous sulfate solution which is directed to a sulfate crystallization unit. Anhydrous sulfate salts are crystallized from the aqueous sulfate solution to form sulfate salt crystals comprising sulfate and at least one alkali metal. In the chloride salt crystallization unit, chloride salt is crystallized to form chloride salt crystals. A purge from the chloride salt crystallization unit is directed to the hydrous salt crystallization unit.
