Titanium tetrachloride, for example, is added to an anhydrous liquid reaction medium containing one or more alkali metals or alkaline earth metals as reductants. The metal reductants are dispersed as very small globules in the liquid by cavitation of the liquid reaction medium, such as by application of high intensity ultrasonic vibrations or high-shear mixing to the reaction vessel. Continued cavitation of the liquid medium affects relatively low temperature reduction of the precursor halide(s) to produce a titanium-containing product such as titanium metal, a titanium alloy or compound, or a titanium matrix-ceramic composite material, or the like.Type: GrantFiled: August 17, 2006Date of Patent: November 25, 2008Assignee: GM Global Technology Operations, Inc.Inventors: Ion C.

Publication number: 20080241040Abstract: Crystalline scintillator materials comprising nano-scale particles of metal halides are provided. The nano-scale particles are less than 100 nm in size. Methods are provided for preparing the particles. In these methods, ionic liquids are used in place of water to allow precipitation of the final product. In one method, the metal precursors and halide salts are dissolved in separate ionic liquids to form solutions, which are then combined to form the nano-crystalline end product. In the other methods, micro-emulsions are formed using ionic liquids to control particle size.Type: ApplicationFiled: March 26, 2007Publication date: October 2, 2008Inventors: Brent Allen Clothier, Sergio Paulo Martins Loureiro, Alok Srivastava, Venkat Subramaniam Venkataramani

Patent number: 7361325Abstract: A substantially dried XF•nH2O2 product is produced by method(s) wherein a feed solution comprised of (i) a XF composition wherein X is K, Na+ or NH4+ and n is an integer from 1 to 3, (ii) hydrogen peroxide (H2O2), (iii) a fluid carrier component and (iv) a potassium bifluoride (KHF2) catalyst, is atomized as it enters a desiccation/evaporation chamber. The atomized feed solution coats fluidized particles passing through the desiccation/evaporation chamber. The coated fluidized particles are dried by a pre-heated gas stream and thereby creating fluid-bed particles that are coated with a layer of the XF•nH2O2 compound. The resulting XF•nH2O2 coated fluid-bed particles are then subjected to disintegration forces that serve to break substantial portions of the layer of dried XF•nH2O2 material from the outer surfaces of he individual fluid-bed particles. These dried XF•nH2O2 are then recovered as the product of these production methods.Type: GrantFiled: December 29, 2004Date of Patent: April 22, 2008Assignee: GeoStim Group LLCInventor: Vladimir Marakov

Patent number: 7217402Abstract: A method of producing metal chlorides is disclosed in which chlorine gas is introduced into liquid Cd. CdCl2 salt is floating on the liquid Cd and as more liquid CdCl2 is formed it separates from the liquid Cd metal and dissolves in the salt. The salt with the CdCl2 dissolved therein contacts a metal which reacts with CdCl2 to form a metal chloride, forming a mixture of metal chloride and CdCl2. After separation of bulk Cd from the salt, by gravitational means, the metal chloride is obtained by distillation which removes CdCl2 and any Cd dissolved in the metal chloride.Type: GrantFiled: August 26, 2005Date of Patent: May 15, 2007Assignee: United States of America Department of EnergyInventors: William E. Miller, Zygmunt Tomczuk, Michael K. Richmann

Patent number: 7195740Abstract: A method and apparatus for removing BHP contaminants (alkali hydroxide and H2O2) from a recycled aqueous alkali chloride solution stream before the stream is fed to a chloralkali cell so that the contaminants do not impair the operation of a chloralkali cell. Unwanted alkali hydroxide within the recycled alkali chloride brine solution is reacted with chlorine gas and converted into an alkali chloride, which is useful in the operation of the chloralkali cell, and oxygen gas, which is outgassed from the system. Any H2O2 remaining in the recycled stream after elimination of the alkali hydroxide is reacted with chlorine to form HCl and oxygen gas. The HCl raises the pH of the brine solution, after which the pH may be adjusted by the addition of supplemental alkali hydroxide.Type: GrantFiled: March 29, 2004Date of Patent: March 27, 2007Assignee: The Boeing CompanyInventors: Thomas L. Bunn, Stephen C. Hurlock, Alan Z. Ullman

Patent number: 7175708Abstract: Methods and apparatus are provided for the removal and purification of the water and salt by-products from spent BHP emitted from a lasing process. The apparatus comprises a liquid processing system that freezes the water and salt by-products into a slurry, and then separates out the water (as ice) and salt components by filtering in a centrifuge. In order to remove as much residual BHP from the wet mixed ice-salt component as possible, a heat source is used to partially melt ice crystals, thereby generating an aqueous rinsing liquid on the surface of the wet mixed ice-salt crystals. The applied centrifugal force causes a continual displacement of the liquid film wetting the surface, so that it becomes progressively diluted. As such, the purification of the mixture of ice and salt crystals is implemented with an aqueous (water) rinse that is unaffected by the sub-freezing temperatures within the centrifuge.Type: GrantFiled: July 28, 2005Date of Patent: February 13, 2007Assignee: The Boeing CompanyInventors: David Stelman, Steven M.
