|---|---|---|
| 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 |
| 20100008846 | METHOD FOR PRODUCING AMMONIUM HEPTAMOLYBDATE - A method for preparing ammonium heptamolybdate with the steps of: | 01-14-2010 |
| 20100028250 | METHOD FOR PRODUCTION OFAMMONIUM PARATUNGSTATE TETRAHYDRATE AND HIGHLY PURE AMMONIUM PARATUNGSTATE TETRAHYDRATE - The invention is directed to a method for the production of ammonium paratungstate tetrahydrate by thermal treatment of ammonium paratungstate decahydrate in an aqueous suspension. The ammonium paratungstate tetrahydrate can be produced with high purity and high yield. The production method may furthermore be carried out in a simple and energy-efficient manner. | 02-04-2010 |
| 20100098619 | METHOD FOR PRODUCING AMMONIUM PARATUNGSTATE HYDRATES AND AMMONIUM PARATUNGSTATE DECAHYDRATE - The invention is directed to a process for the continuous preparation of ammonium paratungstate hydrate by back reextraction of a tungsten-laden organic phase with an ammonia-containing aqueous solution in a mixer-settler apparatus. The reextraction is carried out at an NH | 04-22-2010 |
| 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 |
| 20110070148 | METHOD FOR PRODUCTION OF AMMONIUM PARATUNGSTATE TETRAHYDRATE AND HIGHLY PURE AMMONIUM PARATUNGSTATE TETRAHYDRATE - The invention is directed to a method for the production of ammonium paratungstate tetrahydrate by thermal treatment of ammonium paratungstate decahydrate in an aqueous suspension. The ammonium paratungstate tetrahydrate can be produced with high purity and high yield. The production method may furthermore be carried out in a simple and energy-efficient manner. | 03-24-2011 |
| 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 |
