Patent number: 9127333Abstract: A method and system for producing an alloy using a flowing stream of superheated halide vapor to flash vaporize liquid halides forming a mixture of gases in predetermined and controllable ratios. The mixture of gases are introduced into a flowing stream of liquid alkali or alkaline earth metal or mixtures to establish a reaction zone where the mixture of gases is reduced to an alloy and a salt. The liquid metal is in a sufficient amount in excess of stoichiometric to maintain substantially all the alloy and salt below the sintering temperatures thereof away from the reaction zone. Equipment for practicing the method is also disclosed. The system relates to alloys of B, Be, Bi, C, Fe, Ga, Ge, Hf, In, Mo, Nb, P, Pb, Re, S, Sb, Si, Sn, Ta, Ti, V, W and Zr.Type: GrantFiled: April 25, 2007Date of Patent: September 8, 2015Inventors: Lance Jacobsen, Adam Benish

Publication number: 20110103997Abstract: A method of increasing the apparent density of agglomerated ligmental titanium or titanium alloy powder produced by the subsurface reduction of titanium tetrachloride vapor or a mixture of titanium tetrachloride and other halide vapors in a flowing stream of alkali or alkaline earth metal or mixtures thereof having a first apparent density after distillation is disclosed. The agglomerated ligmental titanium or titanium alloy powder is introduced into an attriting system wherein the agglomerated ligmental titanium or titanium alloy powder is attrited until the powder becomes more spherical than ligmental and the first apparent density is increased by a factor of from about 3 to about 8.

Patent number: 7753989Abstract: A method of producing passivated Ti or Ti alloy particles with oxygen concentrations of less than about 900 parts per million (ppm), which includes introducing a halide vapor of Ti or the metal constituents of the alloy at sonic velocity or greater into a stream of liquid alkali or liquid alkaline earth metal or mixtures thereof forming a reaction zone in which the halide is reduced by the liquid metal present in sufficient excess of stoichiometric such that Ti or Ti alloy powder from the reduction of the halide by the liquid metal is friable. After filtration and distillation excess liquid metal is removed from the Ti or Ti alloy powder that is then maintained at elevated temperature for a time sufficient to grow the particles to average diameters calculated from BET surface area measurement greater than about one micron. After cooling the Ti or Ti alloy powder to temperature of about 80° C.Type: GrantFiled: December 22, 2006Date of Patent: July 13, 2010Assignee: Cristal US, Inc.Inventors: William Ernst, Lance Jacobsen

Patent number: 7632333Abstract: A method of separating metal particulates from a slurry of original constituents of liquid metal and metal particulates and salt particulates is disclosed. The metal and salt particulates are concentrated by removing at least some of the liquid metal, and then, liquid metal or a liquid of the original salt constituent or a mixture thereof is passed through the particulates at a temperature greater than the melting point of the original salt constituent to further concentrate the metal particulates. The metal particulates are then separated from the remaining original constituents or a mixture of the salt constituent. Density differences between the liquid metal and salt are also used to facilitate separation.Type: GrantFiled: September 3, 2003Date of Patent: December 15, 2009Assignee: Cristal US, Inc.Inventors: Richard P. Anderson, Armstrong Donn, Lance Jacobsen

Patent number: 7501007Abstract: A system and method of separating metal powder from a slurry of liquid metal and metal powder and salt is disclosed in which the slurry is introduced into a first vessel operated in an inert environment when liquid metal is separated from the metal powder and salt leaving principally salt and metal powder substantially free of liquid metal. The salt and metal powder is transferred to a second vessel operated in an inert environment with both environments being protected from contamination. Then the salt and metal powder are treated to produce passivated powder substantially free of salt and liquid metal. The method is particularly applicable for use in the production of Ti and its alloys.Type: GrantFiled: September 3, 2003Date of Patent: March 10, 2009Assignee: Cristal US, Inc.Inventors: Richard P.

Publication number: 20080064912Abstract: A process for preparing a layered composition has been developed. The composition comprises an inner core and an outer layer comprising a molecular sieve. The process involves providing a slurry comprising inner core particles and sources of the framework elements of the molecular sieve. To this slurry there are added nutrient(s), i.e. framework element sources thereby forming crystals of the molecular sieve which agglomerate onto the inner core. The process is carried out for a time sufficient to form a layer of desired thickness.Type: ApplicationFiled: November 12, 2007Publication date: March 13, 2008Inventors: Lance Jacobsen, Brian Konrad, David Lesch, Julio Marte, Beckay Mezza
