| titleOfInvention | Manufacture of noble metal fine particles |
| abstract | PURPOSE: To manufacture fine particles having monodisperse and narrow range of particle size distribution with controlled particle diameter by heating chloride of gold, platinum, palladium and ruthenium, keeping its temp. and controlling hydrogen reduction ratio. n CONSTITUTION: For example, the fine and uniform gold chloride crystal is charged into a quartz boat and this is put in center of a quartz tube horizontally positioned, and after heating under inert gas atmosphere at the prescribed temp., hydrogen gas is supplied and gold ion is reduced to complete the reaction. The quartz boat is taken out and the fine gold particles are filtered by using pure water and successively, water washing is executed and further, after substituting water with ethanol, this is dried at the room temp. to obtain the fine gold particles. n COPYRIGHT: (C)1990,JPO&Japio |
