Ultra-fine amorphous powders in (Fe, Co, Ni)-B binary and ternary systems were produced by the chemical reduction method. The powders have a spherical shape with diameters ranging from 5 to 50 nm. The reaction consists mainly of the process of producing Me2B and Me(Me = Fe, Co, Nil. Fully dense bulk
