摘要： The invention relates to the use of a powder composition comprising at least 95% by weight of magnetite (Fe3O4) particles as a magnetisable component in a medium for magnetically storing information. At least 99,9% by weight of the magnetite particles have a particle size of less than 5 μm, and the magnetite particles have a polyhedral shape and essentially isotropic magnetic properties. The magnetite particles have a saturation magnetisation of 75-95 emu/g at 10 kOe, a remanence of 20-40 emu/g and a coercivity of 250- 500 Oe. The invention also relates to the medium for magnetically storing information comprising magnetite particles.

摘要： A dry magnetic toner is formed of magnetic toner particles comprising a binder resin and magnetic iron oxide particles. The magnetic toner is provided with excellent developing performances and transferability by controlling the presence of isolated iron-containing particles and containing a high percentage of spherical particles, the amount of which is controlled relative to the weight-average particle size of the magnetic toner and a content of particles of 3 µm or below in the magnetic toner.

摘要： A process for preparing a powder coated with a multilayer film by coating the surface of a powder of a metal or a metal oxide as a substrate with a plurality of layers of a metal oxide, wherein the metal oxide layer or the like is formed by decomposition of a metal salt as an inexpensive starting material. For this process, the decomposition or the like of a metal salt under the conditions producing an acid or the like as a by-product is conducted so that powder particles are not attacked by the acid or the like. The coated powder is characterized in that at least one layer is formed of a metal hydroxide or a metal oxide formed by the hydrolysis of a metal alkoxide and that a layer overlying the metal hydroxide or metal oxide layer(s) is a coating layer formed of a metal hydroxide or a metal oxide formed by a reaction of a metal salt, for example, neutralization or heat decomposition. The heat treatment of the metal hydroxide layer or the metal oxide layer formed by the hydrolysis of a metal alkoxide causes the layer to be converted to a dense metal oxide layer.
