The application of carbon fluoride chloride in dry lubricant compositions is disclosed. The material offers a substantial improvement in lubricating properties over prior art carbon fluoride dry lubricants. The improved lubricant is comprised of carbon fluoride chloride of the general formula (C.sub.y F.sub.x Cl.sub.z).sub.n wherein y is 1 or 2, x is greater than 0 to 1.2, z is 0.1 and n defines an infinitely large two dimensional array of repeating units occurring in this molecule of high molecular weight. The resulting lubricant has improved lubricating properties over graphite, MoS.sub.2 and carbon monofluoride.

A novel high energy density aqueous cell exhibiting superior electrochemical properties is described. The use of the novel cathode composition, (C.sub.y F.sub.x Cl.sub.z).sub.n, permits the construction of a novel high energy density aqueous cell comprised of an anode, an alkaline electrolyte and a cathode, said cathode comprised of carbon fluoride chloride of the type (C.sub.y F.sub.x Cl.sub.z).sub.n : wherein y is 1 or 2; x is greater than 0 up to about 1.2; z is greater than 0 up to 0.1; and n denotes an infinitely large two dimensional array of C.sub.y F.sub.x Cl.sub.z units. The carbon fluoride chloride is composed of carbon, fluorine and chlorine, wherein the carbon can be chosen from the group consisting of graphite, coke, needle coke, charcoal, activated carbon, carbon blacks and the like. The carbon fluoride chloride described herein can be made in several ways, e.g. carbon can be reacted with chlorine monofluoride, ClF, to produce (C.sub.y F.sub.x Cl.sub.z).sub.n or with mixtures of chlorine, Cl.sub.2, and fluorine, F.sub.2, to produce (C.sub.y F.sub.x Cl.sub.z).sub.n.

A process is disclosed for producing fluorinated carbon (CF.sub.x) admixed which can be used in a lithium battery to eliminate low voltage at the beginning of discharge. The process uses a thick carbon bed to assure proper degree and type of underfluorination of the CF.sub.x. The inhomogeneous fluorinated carbon produced is a fully, or overfluorinated CF.sub.x with a small amount of underfluorinated material to eliminate voltage suppression in Li/CF.sub.x batteries.

A method for treating process waste consisting of uranium hexafluoride, UF.sub.6, molybdenum hexafluoride, MoF.sub.6 and molybdenum oxytetrafluoride, MoOF.sub.4 is provided wherein the foregoing mixture is hydrolyzed in an aqueous solution of ammonium carbonate and ammonium hydroxide. The resulting mother liquor is digested at 60.degree.-80.degree. C. to drive off carbon dioxide and convert the ammonium uranyl carbonate, (NH.sub.4).sub.4 UO.sub.2 (CO.sub.3).sub.3 to ammonium diuranate, (NH.sub.4).sub.2 U.sub.2 O.sub.7. The pH is maintained above 9 to prevent premature precipitation of the molybdenum values as molybdic acid or uranyl molybdate. The ammonium diuranate which forms as a yellow solid is filtered, slurried in aqueous ammonium hydroxide, filtered and dried. The yield is quantitative. Pyrolysis results in conversion of the diuranate salt to uranium oxide, U.sub.3 O.sub.8, of suitable purity to be recycled in the uranium hexafluoride production process. The combined filtrates which contain the molybdenum values and ammonium fluoride by-product are diluted, and stirred, with 95% ethanol to precipitate white, crystalline, ammonium molybdate, (NH.sub.4).sub.2 MoO.sub.4. The ammonium fluoride remains soluble. The ammonium molybdate is filtered, dried and calcined at 600.degree. C. for 2 hours to yield molybdenum trioxide, MoO.sub.3 in &gt;90% yield and essentially free of uranium contamination. Fluoride contamination in either of the reprocessed materials is minimal.

Separation and recovery of molybdenum values from uranium process waste

A cell and process is provided for the production of fluorine comprising electrolyzing a liquid mixture of fluorides of alkali metal, ammonium and hydrogen fluoride. The cell anode comprises a stock of anode plates with internal passages or it may comprise a carbon shape provided with grooves and passages and fitted to a central conductor which conducts current from the exterior of the cell to the carbon anode plates within the cell. The anode having a substantially expanded working surface has the capability of removing fluorine internally. A louvered cathode permits most of the hydrogen to be vented away from the zone between the electrodes through which current passes thus reducing the ohmic voltage loss. The cathode, rather than being louvered, can be expanded metal or punched sheet or gauze. The anode, cathode and barrier may be cylindrical in form although other shapes, for instance rectangular or square in cross section or even of hexagonal section, may be used if desired. Combination of the segmented anode design with a louvered cathode provides a unique cell for fluorine production because virtually the same electrolysis condition exists at any part of the anode and cathode.
