| 20080311018 | Materials Purification by Treatment with Hydrogen-Based Plasma - The present invention relates to a purification method for removing oxygen from materials, especially boron, by hydrogen-based plasma treatment. | 12-18-2008 |
| 20100278705 | INNOVATIVE CUT-AND-FEED OPERATION FOR ENHANCING THE PERFORMANCE OF ION-EXCHANGE CHROMATOGRAPHIC SEPARATION - The present invention relates to a process of enriching element content in stable isotopes of light elements in ion-exchange chromatography. The process comprises development of band of light elements in a chromatographic column; elution of said band in a discontinuous basis so as to disconnect said chromatographic column at particular stage; and finally the process comprises of regeneration step. | 11-04-2010 |
| 20120301383 | COMPOSITION OF MATTER TAILORING: SYSTEM I - The present invention relates to new compositions of matter, particularly metals and alloys, and methods of making such compositions. The new compositions of matter exhibit long-range ordering and unique electronic character. | 11-29-2012 |
| 20130045152 | Elemental Boron by Reduction of Boron Halides by metals and their borides - The quest for making pure boron has been continuing for over 200 years. Most common method has been by hydrogen reduction of boron halides on a hot filament, and this has not been an economical approach. Other techniques using magnesiothermic reduction or electrolysis of oxide compounds of boron produced impure boron. Present invention describes techniques of making pure boron in the amorphous as well as crystalline form—applying thermochemical principles in an efficient manner. The present invention shows that boron halides can be reduced by alkali metal, alkaline earth metal, aluminum or silicon, as well as by alkaline earth borides, aluminum borides, silicon borides into pure elemental boron. | 02-21-2013 |
| 20130095023 | METHOD FOR CYCLICALLY PREPARING MONOMER BORON AND COPRODUCING POTASSIUM CRYOLITE USING POTASSIUM FLUOBORATE AS INTERMEDIATE MATERIAL - A method for cyclically preparing monomer boron and coproducing potassium cryolite using potassium fluoborate as an intermediate material, which includes following steps: A) adding hydrofluoric acid to boric acid or boron oxide to enable a reaction to form fluoboric acid; B) adding a potassium sulphate aqueous solution to the fluoboric acid to enable a reaction to form the potassium fluoborate; C) putting the potassium fluoborate into a reactor, adding aluminium to react with the potassium fluoborate to form the monomer boron and potassium cryolite; D) extracting the potassium cryolite, sending the potassium cryolite to a rotary reaction kettle together with concentrated sulphuric acid to enable a reaction to form hydrogen fluoride gas and aluminium potassium sulphate, potassium sulphate, collecting the hydrogen fluoride gas and dissolving it into water to obtain the hydrofluoric acid; E) recycling the obtained hydrofluoric acid to Step A to leach the boric acid or boron oxide. | 04-18-2013 |
| 20130095024 | METHOD FOR CYCLICALLY PREPARING MONOMER BORON AND COPRODUCING SODIUM CRYOLITE USING SODIUM FLUOBORATE AS INTERMEDIATE MATERIAL - A method for cyclically preparing monomer boron and coproducing sodium cryolite using sodium fluoborate as an intermediate material, which includes the following steps: A) adding hydrofluoric acid to boric acid or boron oxide to enable a reaction to form fluoboric acid; B) adding a sodium carbonate aqueous solution to the fluoboric acid to enable a reaction to form the sodium fluoborate; C) putting the sodium fluoborate into a reactor, adding aluminium to react with the sodium fluoborate to form the monomer boron and sodium cryolite; D) extracting the sodium cryolite, sending the sodium cryolite to a rotary reaction kettle together with concentrated sulphuric acid to enable a reaction to form hydrogen fluoride gas and aluminium sodium sulphate, collecting the hydrogen fluoride gas and dissolving it into water to obtain the hydrofluoric acid; E) recycling the obtained hydrofluoric acid to Step A to leach the boric acid or boron oxide. | 04-18-2013 |
