20090255372 | RECYCLING OF SUPERALLOYS WITH THE AID OF AN ALKALI METAL SALT BATH - The invention relates to a process for recovering valuable metals from a superalloy which has the steps of digesting the superalloy in a salt melt. The salt melt contains 60-95% by weight of NaOH and 5-40% by weight of Na | 10-15-2009 |
20100059707 | Mixed metal hydroxides and their preparation and use - The present invention relates to a particulate mixed metal hydroxide that includes nickel, cobalt and aluminium. The powder particles have a core of nickel/cobalt hydroxide, and a surface that is coated with amorphous aluminium hydroxide. A process for the continuous preparation of such mixed metal hydroxides is also described. The process includes precipitating aluminium hydroxide in the presence of a nickel/cobalt mixed hydroxide in a tube reactor. The mixed metal hydroxides of the present invention may be used to prepare active materials for positive electrodes of a secondary battery. | 03-11-2010 |
20100102282 | PULVERULENT COMPOUNDS, PROCESSES FOR THE PREPARATION THEREOF AND THE USE THEREOF IN ELECTROCHEMICAL APPLICATIONS - The present invention relates to pulverulent compounds of the formula Ni | 04-29-2010 |
20100310869 | POWDER NiaMbOx(OH)y COMPOUNDS, PROCESSES FOR MAKING THE SAME, AND USES THEREOF IN BATTERIES - Powdery compounds of the formulation Ni | 12-09-2010 |
20110123709 | PROCESS FOR PRODUCING PURE AMMONIUM PERRHENATE - A process for preparing a pure ammonium perrhenate includes producing a first aqueous suspension containing an ammonium perrhenate. A stoichiometric amount of a nitric acid is added to the first aqueous suspension so as to produce a second suspension. The second suspension is introduced into a cathode space of an electrolysis cell. The electrolysis cell is divided by a cation-exchange membrane into the cathode space and an anode space. The nitric acid is cathodically reduced to a nitrous acid in the cathode space by applying an electric potential. The nitrous acid is reacted with ammonium ions of the ammonium perrhenate so as to form an aqueous perrhenic acid. Potassium ions are removed from the aqueous perrhenic acid. At least a stoichiometric amount of ammonia is added to the aqueous perrhenic acid so as to produce the pure ammonium perrhenate. | 05-26-2011 |
20110180748 | POWDERED NIAM1 BM2C(O)X(OH)YCOMPOUNDS, METHOD FOR THE PRODUCTION THEREOF AND USE THEREOF IN BATTERIES - The invention is directed to a pulverulent compound of the formula Ni | 07-28-2011 |
20110300470 | DEVICE AND METHOD FOR THE PRODUCTION OF COMPOUNDS BY PRECIPITATION - The invention relates to a device and a method for the production of compounds by precipitation of solids from solutions, the physical and chemical properties of the solid particles formed on precipitation being flexible and can be independently fixable. Custom products can thus be produced with very high space-time yields and a particulate nickel/cobalt mixed hydroxide of formula Ni | 12-08-2011 |
20120045647 | TUNGSTIC ACID POWDER CONSISTING OF SPHERICAL TUNGSTEN PARTICLES AND METHOD FOR PRODUCING SAME - Process for the production of a powdered spherical tungstic acid by acidification of an aqueous alkaline tungstate solution with mineral acid at elevated temperature, preferably in a continuous stirred tank or a cascade of at least 2 continuous stirred tanks, and tungstic acid obtainable in this way, which is characterised by a high bulk density and spherical morphology. | 02-23-2012 |
20140138586 | COBALT- AND MOLYBDENUM-CONTAINING MIXED OXIDE CATALYST, AND PRODUCTION AND USE THEREOF AS WATER GAS SHIFT CATALYST - A mixed oxide catalyst includes a support material selected from the group comprising aluminum oxide, magnesium oxide, titanium oxide, and mixtures of aluminum oxide, magnesium oxide, and titanium oxide, and a catalyst active component comprising cobalt oxide and molybdenum oxide. The catalyst active component is nanodispersed in the support material. | 05-22-2014 |
20140301939 | PROCESS FOR PRODUCING PURE AMMONIUM PERRHENATE - The present invention provides an ammonium perrhenate containing less than 5 ppm of potassium. | 10-09-2014 |
