Magnetic fine particles of epsilon' iron carbide |
| abstract |
Novel acicular magnetic fine particles of ε′ iron ncarbide represented by the composition formula: ε′-Fe 2.2 C nhaving an average particle size of 0.01 to 0.2 µm is prepanred by reacting α-Fe powder having an average particle size nof 0.01 to 0.2 µm with a reducing and carbonizing agent ncontaining carbon at a temperature of not higher than 250°C. |
