METHOD OF PREPARING A POWDER IN A PLASMA ARC AND DEVICE FOR CARRYING OUT SAID METHOD |
摘要 |
Methods are known for continuously preparing a powder by reacting at least two reagents in a plasma arc, at least one first and one second reagent being fed to the plasma arc which is maintained by a voltage applied between a first and a second electrode. At least the first reagent is electrically conductive and is used as the first electrode. A device suitable for this purpose comprises a feed arrangement for feeding at least the first reagent to a plasma chamber having an interior which tapers in the direction of a passage lying opposite the feed opening. In order to provide on this basis a simple and economical method for the continuous and reproducible preparation of a powder by reacting at least two reagents in a plasma arc (9) and to propose a device for this purpose, the first reagent is fed in fluid form to the plasma arc (9) and the feed arrangement comprises a vessel which accommodates the first reagent and is provided with an outlet on its underside facing the feed opening in the plasma chamber (6). |
