    摘要: A glass ceramic and a preparation method thereof include a step of melting calcined electrolytic manganese slag to obtain molten glass. The molten glass is sequentially molded, nucleated, and crystallized to obtain the glass ceramic. The calcined electrolytic manganese slag is taken as a raw material, so that harmful gases are not generated in the raw material melting process, and secondary pollution is not caused. The preparation method provided by the present invention has the advantages of simple operation, high utilization rate of electrolytic manganese slag and low cost. Moreover, the prepared glass ceramic has good mechanical properties and corrosion resistance.

    摘要: Described are methods of removing aluminum fluoride contaminants from aluminum, anodized aluminum, and sprayed ceramic surfaces. Hydrofluoric acid, long known to be effective at removing certain contaminants, has not been used to dissolve aluminum fluoride on aluminum-containing surfaces because the hydrofluoric acid strongly attacks such surfaces, and consequently damages sensitive components. Methods used in accordance with some embodiments remove aluminum fluoride using a mixture of hydrofluoric acid and one or more anhydrous acid. Suitable anhydrous acids include acetic acid.

    摘要: Metallic elements such as iron, manganese and refractory metals are recovered from ores, slags, silicate residues, etc., by electrodeposition from a melt comprising a chloride phase and a silicate phase. The cathode is submerged in the chloride phase while the anode is in contact with both the chloride and the silicate phases. Borate, phosphate or fluoride salts are added to the melt to promote diffusion of metallic ions from the silicate phase to the chloride phase.

    摘要: In a method for removing a substance from a feedstock comprising a solid metal or a solid metal compound, the feedstock is contacted with a fused-salt melt. The fused-salt melt contains a fused salt, a reactive-metal compound, and a reactive metal. The fused salt comprises an anion species which is different from the substance, the reactive-metal compound comprises the reactive metal and the substance, and the reactive metal is capable of reaction to remove at least some of the substance from the feedstock. A cathode and an anode contact the melt, and the feedstock contacts the cathode. An electrical current is applied between the cathode and the anode such that at least a portion of the substance is removed from the feedstock. During the application of the current, a quantity of the reactive metal in the melt is maintained sufficient to prevent oxidation of the anion species of the fused salt at the anode. The method may advantageously be usable for removing the substance from successive batches of the feedstock, where the applied current is controlled such that the fused-salt melt after processing a batch contains the quantity of the reactive metal sufficient to prevent oxidation of the anion species at the anode.

    摘要: THIS INVENTION PROVIDES A METHOD FOR OBTAINING MOLTEN MANGANESE METAL BY ELECTRLYSING A MOLTEN MIXTURE OF METAL HALIDES COMPRRISING A MANGANESE HALIDE AND A BATH MIXTURE COMPRISING A HALIDE OF A REACTANT METAL, AN ALKALI METAL HALIDE AND AN ALKALINE EARTH METAL HALIDE. MANGANESE METAL IS OBTAINED IN A MOLTEN PHASE BELOW THE MOLTEN MIXTURE OF METAL HALIDES AND ELEMENTAL HALOGEN IS EVOLVED AT THE ANODE. THE REACTANT METAL IS ELECTRLYTICALLY REDUCED AT THE CATHODE. THE ANODE AND CATHODE ARE BOTH INERT AND IMMERSED IN THE MOLTEN MIXTURE OF METAL HALIDES THE HALIDES ARE PREFERABLY CHLORIDES, BROMIDES OR

    IODIDES. THE REACTANT METAL CAN BE ANY CATHODICALLY REDUCIBLE METAL WHICH CAN REPLACE MANANESE FROM MANGANESE HALIDE IN THE MOLTEN SALT BATH, BUT IS PREFERABLY ALUMINUM OR MAGNESIUM.
