AbstractThe acicular metal magnetic recording powders was prepared in fluidized bed reactor. The results of characterizing with XRD, TEM, VSM etc show that the coercivity of metal powders can be improved by the H-2+H2O reduction process. At 460 degreesC the coercivity of the metal powders is 1520Oe, being 5.6% higher than that of the metal powder produced by the traditional H-2 reduction process. The fluidized bed reactor is suitable for this process of industry production. It has a number of advantages such as uniform reaction temperature, good gas-solids contacting, and freedom from sintering of the particles.; The acicular metal magnetic recording powders was prepared in fluidized bed reactor.
