Abstract
A process for producing a magnesium-reactive metal alloy, for example a calcium-magnesium alloy, by electrodepositing the reactive metal from a molten salt bath containing a chloride of said reactive metal directly into a molten pool of magnesium.
Claims14
A process for producing a molten alloy of magnesium and calcium, said calcium being produced by electrolysis of a molten salt bath comprising the chloride of calcium, wherein the said alloy is formed in a molten magnesium cathode,
- said process comprising providing a molten magnesium metal cathode in said molten bath;
- electrolyzing a molten halide salt bath containing calcium chloride, whereby said calcium produced by the electrolysis is deposited in said molten magnesium cathode and alloys therewith;
- and removing the molten alloy from said bath.
A process for producing a molten alloy of magnesium and a reactive metal said reactive metal being produced by electrolysis of a molten salt bath comprising the chloride of calcium, lithium, sodium, or potassium, wherein the said alloy is formed in a molten magnesium cathode,
- said process comprising providing a molten magnesium metal cathode in said molten bath;
- electrolyzing a molten halide salt bath containing the chloride salt of the reactive metal, whereby said reactive metal produced by the electrolysis is deposited in said molten magnesium cathode and alloys therewith;
- and removing the molten alloy from said bath,
- and wherein the process is operated using an electrical element comprising a solid magnesium rod enclosed in a tube made of an inert material and cooled by an inert gas, said element being in electrical contact with the molten magnesium cathode.
A process for preparing a molten calcium-magnesium alloy comprising electrodepositing calcium from a molten chloride salt bath containing calcium chloride directly into a molten pool of magnesium, wherein said magnesium is a molten cathode for the electrodeposition.
