| titleOfInvention | Plate magnetite particle powder and production thereof |
| abstract | PURPOSE: To obtain a pore-free plate magnetite particle powder having average diameter and specific surface area being in the prescribed range, free from sintering and having excellent dispersibility in a resin, by subjecting an alkaline suspension containing water-containing iron(III)oxide particle and iron(II) hydroxide to hydrothermal treatment in the presence of sulfuric acid radical at a specific temperature. n CONSTITUTION: An alkaline suspension containing water-containing iron(III)oxide and iron(II)hydroxide is subjected to hydrothermal treatment in the presence of a sulfuric acid radical at 200-300°C to provide the plate magnetite particle. Thereby the aimed pore-free plate magnetite particle powder having 0.5-5μm average diameter and 1.5-6m 2 /g specific surface area and free from sintering is obtained. The obtained particle is preferably used as a material powder for electromagnetic absorption and shield material because of having excellent dispersibility in a vehicle or resin and being ≥0.5μm particle. n COPYRIGHT: (C)1989,JPO&Japio |
