Patent number: 8978962Abstract: A fine particulate flux, an aqueous flux preparation comprising this flux, a method for the manufacture of a coated part of aluminum, aluminum alloys, steel, copper or titanium using such flux, and a method for brazing parts of aluminum or aluminum alloys to parts of aluminum, aluminum alloys, steel, copper or titanium using such flux. The flux can be obtained by sieving, or it can be obtained by removing solids, e.g., in a cyclone, from the drying gases obtained when wet fluxes are dried, especially after their manufacture. Fine particulate flux increases the viscosity of flux preparations comprising the flux dispersed in water or an aqueous or liquid organic carrier.Type: GrantFiled: March 8, 2011Date of Patent: March 17, 2015Assignee: Solvay Fluor GmbHInventors: Placido Garcia-Juan, Hans-Walter Swidersky, Andreas Becker

Patent number: 8889091Abstract: LiPO2F2, an electrolyte salt additive for batteries, is manufactured by the reaction of POF3, PF5 or mixtures thereof, with Li3PO4 forming a reaction mixture comprising LiPO2F2. When POF3 is applied, the reaction mixture which contains essentially only LiPO2F2 is preferably extracted from the reaction mixture with a solvent which also is applicable as solvent for lithium ion batteries. If PF5 is applied, then, depending on the molar ratio of PF5 and Li3PO4, the reaction mixture also contains LiF and/or LiPF6. To isolate pure LiPO2F2 from LiF, the reaction mixture containing essentially only LiPO2F2 and LiF may for example, be extracted with dimethoxyethane, acetone, dimethyl carbonate or propylene carbonate. To isolate pure LiPO2F2 from LiPF6, the reaction mixture containing essentially only these constituents is preferably extracted with a solvent which also is applicable as solvent for the LiPF6 in lithium ion batteries to dissolve and remove LiPF6.Type: GrantFiled: July 29, 2011Date of Patent: November 18, 2014Assignee: Solvay SAInventors: Alf Schulz, Placido Garcia-Juan

Publication number: 20110110844Abstract: Manganese tetrafluoride is prepared by a reaction between manganese difluoride or manganese trifluoride particles and elemental fluorine. During the reaction, surfaces of the particles are rendered fresh, e.g. by mechanical impact on the particles. Thereby, also agglomeration, sintering or vitrification of the particles is prevented. The impact is not so intensive that the particles would be crushed.Type: ApplicationFiled: December 9, 2008Publication date: May 12, 2011Applicant: SOLVAY FLUOR GMBHInventors: Ulrich Seseke-Koyro, Placido Garcia-Juan, Stefan Palsherm, Alf Schulz
