PRODUCTION OF ELECTROCONDUCTIVE FINE POWDER

摘要

PURPOSE:To obtain the fine powder having a superior electroconductivity by adding an aqueous hydrochloric acid solution of Sn chloride and Sb chloride and an alkaline aqueous solution into the water in parallel to each other to maintain the pH and by forming the coprecipitate. CONSTITUTION:The aqueous hydrochloric acid solution of Sn chloride and Sb chloride and the aqueous alkaline solution are added into the water in parallel to each other and the pH of the solution is maintained at 2-6. Next, the resultant coprecipitate is filtered, recovered and calcined.
