| titleOfInvention | Manufacture of magnetic iron powder for magnetic recording |
| abstract | PURPOSE: To obtain excellent needle-like ferromagnetic fine powder containing iron carbide by a method wherein a vapor phase contact carbonizing reaction is performed under the state in which the mixed gas of carbon monoxide and reducing gas is flowing at the linear speed of 2cm/sec. or more. n CONSTITUTION: The needle-like iron oxyhydroxide fine particles deposited and modified on a configulation retaining part are formed into ferromagnetic reducing iron powder by performing a vapor phase reducing reaction using the reducing gas having hydrogen as the main component. Then, said iron powder is formed into ferromagnetic cementite by the vapor phase contact carbonic reaction using the mixed gas of carbon monoxide and reducing gas. The above- mentioned vapor phase contact carbonic reaction is performed under the state wherein the flow speed of the mixed gas of carbon monoxide and reducing gas is maintained at the linear speed of 2cm/sec. or more using an agitative fludized floor or the reactor of a fluidized substance system. As a result, excellent cementite containing needle-like ferromagnetic fine particles can be obtained. n COPYRIGHT: (C)1987,JPO&Japio |
