| titleOfInvention | Metallic magnetic powder |
| abstract | PURPOSE:To obtain the title metal magnetic powder having improved oxidational stability which is suitable for a high density magnetic recording medium by a method wherein the amino-substituted benzene carboxylic acid is carried on the surface of grains. CONSTITUTION:An amino-substituted benzene carboxylic acid compound is carried on the surface of grains. The various compounds shown by a general formula as shown in the diagram can be used as the amino-substituted benzene carboxylic acid compound. For example, the metal magnetic powder mainly composed of needle-like iron (obtained by heat-reducing the heat-dehydrated alpha-FeOOH using reducing gas, and it has the average length of axis of 0.3mum, coercive force (Hc) of 1302Oe, and saturated magnetization (sigma) of 127.8emu/g) is prepared. Said magnetic powder is dipped into an ethanol solution of 1000ml in which 1.5g of anthranilic acid (o-aminobenzene carboxylic acid) is dissolved, and after agitating for three hours at the room temperature while nitrogen gas is being fed, it is filtered, dried up in the air of the room temperature, and the metal magnetic powder having anthranilic acid on the surface of the grain can be obtained. |
