Abstract
The ferromagnetic metal powder is used in computing equipment, electronics and electrotechnics. It has a low specific surface of up to 10 m<2>/g high magnetic parameters (coercive strength Hc= 600-800 0e). It contains a significant quantity of hydride-bonded hydrogen that guarantees its thermo- stability by keeping its magnetic and conducting properties- a Curie temperature 800 degrees C. The amorphous Ferro magnet metal powder includes Ferro magnetic element, boron, adsorbed hydrogen and hydride-bonded hydrogen in quantity of 1 percent. The method for its preparation is as follows: Solutions of the water-soluble salt of the Ferro magnetic element and the boron-hydride is added simultaneously and separately and are mixed in the lower part of a reactor, hence Ferro magnet particles are lifted upwards by the lifting force of hydrogen, as they grow bigger. The device includes a reaction vessel situated in a broadening vessel, as the solutions are added through incoming pipes perpendicular to the axis of the reactionary vessel, and the suspension with the final product is removed from the bottom of the broadening vessel, which is supplied with openings.
