| titleOfInvention | Powder of granular magnetite having high coercive force and its preparation |
| abstract | PURPOSE: To obtain powder of granular magnetite having high coercive force, by applying inner stress to the granular magnetite synthesized from a Fe 2+ -containing aqueous solution by impact and grinding, thereby imparting a strain anisotropy to the magnetite. n CONSTITUTION: A granular magnetite (FeO x .Fe 2 O 3 ; 0<x≤1) having a coercive force of ≤120 Oe is prepared from an aqueous solution containing Fe 2+ by wet synthesis, etc. The granular magnetite is applied with internal stress by the impact and grinding force using a vibration mill or rotary mill, and a magnetite particle having an coercive force of ≥130 Oe and imparted with strain anisotropy can be prepared. A powder of granular magnetite having high coercive force and suitable as a magnetic recording medium can be prepared by this process without adding foreign metals. n COPYRIGHT: (C)1984,JPO&Japio |
