FIELD: powder metallurgy.
SUBSTANCE: technology for producing fine molybdenum powders, which are used in the production of carbide materials and molybdenum ferroalloys. The powder is obtained from waste molybdenum, metal grade “МЧ” by electroerosive dispersion in distilled water. Voltage on the electrodes is maintained at 70-230 V, capacitance of the discharge capacitors is 40-55 mcF, and the pulse repetition rate is 60-100 Hz.
EFFECT: obtaining a powder of the correct spherical or elliptical shape in an environmentally friendly, inexpensive and safe way.
