| 20100080746 | METHOD FOR PRODUCING HIGHER SILANES - The invention relates to a method for producing dimeric and/or trimeric silicon compounds, in particular silicon halogen compounds. The claimed method is also suitable for producing corresponding germanium compounds. The invention also relates to a device for carrying out said method to the use of the produced silicon compounds. | 04-01-2010 |
| 20100266489 | REMOVAL OF FOREIGN METALS FROM INORGANIC SILANES - The invention relates to a method for the treatment of a composition containing inorganic silanes and at least one foreign metal and/or a compound containing a foreign metal, wherein the composition is brought in contact with at least one adsorption agent, and for obtaining the composition, in which the content of foreign metal and/or of a compound containing a foreign metal is reduced, and to a corresponding composition having a reduced foreign metal content, and further to the use of organic resins, activated carbons, silicates, and/or zeolites for the reduction of foreign metals and/or compounds containing foreign metals in compositions of inorganic silanes. | 10-21-2010 |
| 20100270296 | LARGE CONTAINER FOR HANDLING AND TRANSPORTING HIGH-PURITY AND ULTRA HIGH PURITY CHEMICALS - The invention relates to an empty container ( | 10-28-2010 |
| 20100274028 | REMOVAL OF POLAR ORGANIC COMPOUNDS AND EXTRANEOUS METALS FROM ORGANOSILANES - The invention relates to a process for treating a composition comprising organosilanes and at least one polar organic compound and/or at least one extraneous metal and/or a compound containing extraneous metal, wherein the composition is contacted with at least one adsorbent and a composition in which the content of the organic polar compound and/or of the extraneous metal and/or of the compound containing extraneous metal is reduced is subsequently obtained, and also to a corresponding composition in which the content of polar organic compounds and/or extraneous metals has been reduced to traces, and to the use of organic resins, activated carbons, silicates and/or zeolites for reducing the amounts of the compounds mentioned. | 10-28-2010 |
| 20100278706 | METHOD FOR REDUCING THE CONTENT IN ELEMENTS, SUCH AS BORON, IN HALOSILANES AND INSTALLATION FOR CARRYING OUT SAID METHOD - The invention relates to a method for reducing the content in elements of the third main group of the periodic system, especially in boron- and/or aluminum-containing compounds of technically pure halosilanes for producing purified halosilanes, especially high-purity chlorosilanes. The invention further relates to an installation for carrying out said method. | 11-04-2010 |
| 20100296994 | CATALYST AND METHOD FOR DISMUTATION OF HALOSILANES CONTAINING HYDROGEN - The invention relates to a catalyst, the use thereof, and a method for dismutation of halosilanes containing hydrogen, in particular chlorosilanes containing hydrogen. | 11-25-2010 |
| 20110052474 | INSTALLATION AND METHOD FOR REDUCING THE CONTENT IN ELEMENTS, SUCH AS BORON, OF HALOSILANES - The invention relates to a method for reducing the content in elements of the third main group of the periodic system, especially in boron- and aluminum-containing compounds of technically pure halosilanes for producing high-purity halosilanes, especially high-purity chlorosilanes. The invention further relates to an installation for carrying out said method. | 03-03-2011 |
| 20110150741 | PRODUCTION OF SILICON BY REACTING SILICON OXIDE AND SILICON CARBIDE, OPTIONALLY IN THE PRESENCE OF A SECOND CARBON SOURCE - The invention relates to a method for producing silicon by reacting silicon oxide at an elevated temperature, silicon carbide and, optionally, a second carbon source being added to the reaction mixture. The invention further relates to a composition that can be used in the disclosed method. The essential part of the invention is the use of silicon carbide as a reaction initiator and/or reaction accelerator during the production of silicon or, alternatively, in nearly equimolar amounts for the production of silicon. | 06-23-2011 |
