Abstract
| Production technology in '2 Metal powders', part of 'Landolt-Börnstein - Group VIII Advanced Materials and Technologies: Numerical Data and Functional Relationships in Science and Technology, Volume 2A1: Powder Metallurgy Data'. | |
| This chapter discusses the production technology of metal powders. With regard to industrial relevance, traditional methods like oxide reduction specifically for iron powder production or electrolytic reduction preferably for copper powder production are still of considerable practical importance or, like thermal decomposition of carbonyls for specialty iron powder production, have only recently acquired increasing industrial application. Basic considerations and industrial realization of electrodeposition of copper powder are discussed in detail. Scanning electron micrographs of different electrolytic copper powders are illustrated. In recent years thermal decomposition of suitable chemical compounds has become a dominating process especially for the large scale production of high quality spherical iron fine powders with particle sizes of less than 10 µm for powder metallurgy purposes and metal injection moulding in particular. |
