摘要： Titanium and zirconium diborides are electrolytically synthesized using a molten sodium salt electrolyte containing cryolite, a sodium alkali, a sodium borate, a sodium halide and a source compound to supply the titanium or zirconium. Substantial refining occurs during the synthesis allowing the use of rutile concentrates as a source of titanium and zircon concentrates as a source of zirconium. The synthesis may be accomplished in a cell open to the atmosphere to produce substantially pure titanium and zirconium diborides.

摘要： Rare earth metal-magnesium or rare earth metal-aluminum alloys are easily produced by subjecting a rare earth oxide and a magnesium or aluminum oxide to the simultaneous electrolytic reduction in a molten salts bath consisting of the fluorides of a corresponding rare earth metal and lithium and, optionally, of barium and/or magnesium or aluminum, by which to deposit out the reduced metals on a cathode. The alloys thus produced, having a relatively low melting point to be molten in the bath at the temperature of electrolysis, can be collected by means of a receptacle placed beneath the cathode, into which they fall.

摘要： A METHOD FOR THE ELECTRODEPOSITIONOF TITANIUM OR ITS ALLOYS IS SHOWN. A FUSED SALT ELECTROLYTIC BATH CONTAINING (1) A MIXTURE OF THE CHLORIDE SALTS OF BARIUM, MAGNESIUM, SODIUM AND CALCIUM HAVING A FREEZING POINT OF LESS THAN 600*C., AND (2) TILANIUM DICHLORIDE, AND IF DESIRED, (3) A SOURCE OF A SUITABLE ALLOY METAL IS ELECTROLYZED. THE ELECTROLYTIC BATH IS MAINTAINED AT A TEMPERATURE OF 400*C. TO 580*C. AND UNDER SUCH CONDITIONS AS WILL MAINTAIN THE MOLAR RATIO OF TILANIUM TRICHLORIDE TO TITANIUM DICHLORIDE LESS THAN 0.5 IN THE VICINITY OF THE ELECTRODE TO BE ELECTROPESPOSITED. A PORTION OF THE BATH IS DESIRABLY MAINTAINED AT A TEMPERATURE ABOVE 500*C. TO CONVERT TITANIUM TRICHLORIDE TO TITANIUM DICHLORIDE TO MAINTAIN THE ABOVE MOLAR RATIO NEAR THE CATHODE. A UNIQUE POLARIZED REGION IS FORMED ABOUT THE CATHODE AS MAGNESIUM IS SIMULTANEOUSLY ELECTRODESPOSITED WITH TITANIUM OR ITS ALLOY AND THEN REHALOGENIZED INTO THE ELECTROLYTE. THE PLATE PRODUCT IS SMOOTH IN SURFACE AND NUMEROUS CAPITAL AND OPERATING EFFICIENCIES ARE ACHIEVED.
