| 423606000 | Group VIB metal (Cr, Mo, or W) | 10 |
| 20090136416 | Method for Producing Nano-Particles of Molybdenum Oxide - Method for producing nano-particles includes vaporizing a precursor material to produce a vapor, directing the vapor into an isolation chamber, combining a quench fluid in a gaseous state with a quench fluid in a liquid state to form a quench fluid stream, contacting the vapor contained in the isolation chamber with the quench fluid stream thereby cooling the vapor to produce the nano-particles in a carrier stream, and removing the nano-particles from the isolation chamber. | 05-28-2009 |
| 20090311169 | COMBUSTION SYNTHESIS AND DOPING OF OXIDE SEMICONDUCTORS - The present invention relates to a method for producing inorganic oxide particles from a precursor material or mixture under combustion synthesis and compositions thereof. The combustion synthesis method is low-cost, low tech, and energy efficient. The combustion synthesized inorganic oxide particles of the method are smaller and exhibits a lower band gap than commercially available specimen of the same chemical composition. | 12-17-2009 |
| 20100233074 | SYNTHETIC METHOD OF TRANSITION METAL OXIDE NANO-PARTICLES - Provided is a method for preparing transition metal oxide nanoparticles from a transition metal as a reactant. The method includes dissolving the transition metal into aqueous hydrogen peroxide to provide peroxi-metallate solution, and then adding a reactive solution containing an alcohol, water and an acid thereto to perform hydrothermal reaction. | 09-16-2010 |
| 20120156127 | PROCEDURE FOR THE SYNTHESIS OF THREADLIKE TUNGSTEN OXIDE W5O14 - The object of the invention is the synthesis of threadlike tungsten oxide W | 06-21-2012 |
| 20140161715 | SULFIDE OXIDATION PROCESS FOR PRODUCTION OF MOLYBDENUM OXIDES FROM MOLYBDENITE - A looping method for production of MoO | 06-12-2014 |
| 20150315035 | ELECTROCHROMIC TUNGSTEN OXIDE FILMS FOR OPTICAL MODULATION AND METHODS OF MAKING THE SAME - The present invention relates to a tungsten oxide film and a method of making the film. The tungsten oxide film has greater than about 85% optical modulation across the visible spectrum. Furthermore, the film may be applied to a substrate that is not heated. | 11-05-2015 |
| 423607000 | Chromium | 4 |
| 20090162273 | Chromium oxide powder having a reduced level of hexavalent chromium and a method of making the powder - A refined chromium oxide powder having a reduced level of hexavalent chromium. The refined powder may be produced by acid and reduction washing or by heat treatment to reduce the hexavalent chromium to a biocompatible level. The powder is then packaged to limit oxidation and absorption of moisture. | 06-25-2009 |
| 20130108543 | METHOD FOR PRODUCING CHROMIUM (III) OXIDE | 05-02-2013 |
| 20130216471 | PROCESS FOR PREPARING CHROMIUM(III) OXIDE - The present invention relates to a process for preparing chromium(III) oxide by reaction of alkali metal chromate with gaseous ammonia, subsequent hydrolysis, isolation of the hydrolysis product and calcination. | 08-22-2013 |
| 20140105812 | PROCESS FOR PREPARING CHROMIUM(III) OXIDE - Process for preparing chromium(III) oxide, which comprises the steps: | 04-17-2014 |
