    Abstract: This disclosure is directed to preparing deashed, precious metal catalyst-containing, partially fluorinated active carbon particles of the formula CF.sub.x, where x ranges from 0.l to about 0.18, preferably using either platinum or silver as the catalyzing material, which can be incorporated into an active layer component of a gas electrode, e.g., an oxygen (air) cathode suitable for use in a chlor-alkali electrolytic cell for producing chlorine and caustic while conserving electrical energy. These particles are deashed to have a B.E.T. surface area of at least 600 m.sup.2 /g and contain less than about 4 weight percent ash. Active electrode layers containing such particles demonstrate an unusually desirable combination of resistance to corrosion, retention of conductive properties and retention of catalytic surface area.

    Abstract: A process, and the compositions produced thereby, wherein an element characterized as aluminum, silicon or chromium, notably aluminum, is alloyed in relatively small concentrations with iron, cobalt or nickel, notably iron or cobalt, or both, which have relatively high Curie temperatures. Small amounts of yttrium, hafnium, zirconium or lanthanium can also be added. Alloys of specified composition are formed into particles of selected size, and the particles then contacted in an atmosphere of controlled oxygen activity at elevated temperature over selected time periods. By treatment with a low oxygen-containing, or low moisture-containing gas an oxide of the alloying element is formed which diffuses to the surface of the particles to form a film. The addition of these elements to the base metal necessarily, and unavoidably reduces the Curie temperature of the metal. However, by limiting the particle size and the amount of oxidation of the alloys, a relatively thin impervious oxide film can be formed on the surface of the alloy particle, and much of the lost Curie temperature can be recovered by the increased magnetization which occurs at the particle core when the oxidized form of the metal migrates, or diffuses, to the surface of the particle.

    Abstract: A process for the exchange of hydrogen isotopes between streams of gaseous hydrogen and liquid water, wherein the streams are brought into contact with one another and a catalyst assembly at a temperature in the range 0.degree.-300.degree. C. The catalyst is an inherently hydrophobic material such as polytetrafluoroethylene, polyethylene, polystyrene, polymethacrylate, polypropylene or carbon black carrying a catalytically active metal, for example, platinum, rhodium and nickel. The inherently hydrophobic support allows the catalytically active metal to catalyze the hydrogen isotope exchange reaction between hydrogen gas and water vapor in the presence of liquid water while retarding loss of activity of the catalytically active metal by contact of the metal catalyst with liquid water. This catalyzed chemical isotope exchange proceeds simultaneously with isotope exchange from water vapor to liquid water by a non-catalyzed, physical evaporation and condensation exchange reaction to effect an overall rapid catalytic isotopic exchange between streams of hydrogen gas and liquid water.
