Abstract: A HIGH-TEMPERATURE DIMESIONALLY STABLE NUCLEAR REACTOR FUEL ELEMENT OF URANIUM MONONITRIDE IN A REFRACTORY METAL MATRIX HAVING EVENLY DISTRIBUTED POROSITY IS PREPARED BY COLD PRESSING A MIXTURE OF A POWDERED REFRACTORY METAL AND POWDERED U2N3, FORMING A BODY WHICH IS THEN DENSIFIED BY HEATING UNDER PRESSURE TO PREVENT COMPLETE DECOMPOSITION OF THE U2N3. THE DENSIFIED BODY IS THEN HEATED TO DECOMPOSE THE U2N3 TO UN, LEAVING EVENLY DISTRIBUTED POROSITY THROUGHOUT THE ELEMENT.

Abstract: Active materials of the invention contain at least one alkali metal and at least one other metal capable of being oxidized to a higher oxidation state. Preferred other metals are accordingly selected from the group consisting of transition metals (defined as Groups 4-11 of the periodic table), as well as certain other non-transition metals such as tin, bismuth, and lead. The active materials may be synthesized in single step reactions or in multi-step reactions. In at least one of the steps of the synthesis reaction, reducing carbon is used as a starting material. In one aspect, the reducing carbon is provided by elemental carbon, preferably in particulate form such as graphites, amorphous carbon, carbon blacks and the like. In another aspect, reducing carbon may also be provided by an organic precursor material, or by a mixture of elemental carbon and organic precursor material.

Abstract: Basic aluminum halides and nitrates having enhanced antiperspirant efficacy are produced by reacting (a) aluminum powder, (b) an aluminum halide or nitrate solution and (c) water at a temperature greater than about 85.degree. C. This reaction is maintained until reaction products having an Al:anion ratio of about 1.2 to 1.8 and a solution solids concentration of about 30-40 wt. % on an anhydrous basis are obtained. The products are characterized as having a Size Exclusion Chromatography Test Band having a relative retention time corresponding to Band II of a Standard Basic Aluminum Chloride Size Exclusion Chromatogram and a Band II percent aluminum value of at least about 50% and a Band III percent aluminum value of less than 20%.

Abstract: A process for the fixation of nitrogen comprising, combining a gaseous nitrogen and oxygen at a total pressure of above 100 atmospheres with a solid oxide which can produce a nitrate, in the presence of an oxide of silicon catalyst for the acceleration of a reaction between nitrogen and oxygen to produce nitrogen oxides, initially heating the combination to a temperature of between 600.degree. C. to 800.degree. C. and below the dissociation pressure of the nitrate to start an exothermic reaction for producing nitrogen oxides from the nitrogen and oxygen and for producing nitrate from the solid oxide and to establish an equilibrium between the nitrogen, oxygen, nitrogen oxides, solid oxide and nitrate. The reacting combination in equilibrium is then cooled and either the nitrate or the nitrogen oxides are removed from the reaction as products.

Abstract: Process for selectively recovering metal chlorides from a gaseous mixture of metal chlorides by contacting the gaseous mixture at a temperature above the condensation point of the mixture with at least one stream of liquid to cool all the mixture to below the freezing point of at least one metal chloride in the mixture, the average velocity of the mixture being at least the pneumatic conveyance velocity at the point of contact. This process provides for recovery of metal chlorides without plugging the apparatus.
