| titleOfInvention | Electrically conductive silicic anhydride fine powder and its production |
| abstract | PURPOSE: To improve electrical conductivity of fine powder of silicic anhydride by simultaneously adding a solution of SnCl 4 and SbCl 3 in hydrochloric acid and an alkali to heated suspension of silicic anhydride so as to maintain the suspension at a specific pH and coating silicic anhydride with SnO 2 and Sb 2 O 3 . n CONSTITUTION: A suspension of silicic anhydride having ≥ about 15nm average particle diameter is heated to about 50-100°C, a solution of SnCl 4 and SbCl 3 in hydrochloric acid and an alkali such as ammonia water are simultaneously added to the suspension while maintaining the suspension at pH 3-9. 50-300wt.% based on silicic anhydride of a coating layer comprising 1-20wt.% Sb 2 O 3 and the rest of SnO 2 is formed, dried and then at about 500-700°C to give electrically conductive fine powder of silicic anhydride. n COPYRIGHT: (C)1991,JPO&Japio |
