FIELD: metallurgy.
SUBSTANCE: powder composed of aggregates of nano-sized particles is subjected to ultrasound dispersion and mechanically mixed at the rate of 250-1000 rpm. Mechanical mixing and ultrasound dispersion are carried out successively at displacement of suspension in closed hydraulic circuit at the rate of 0.06-0.15 m/s. Proposed device comprises high-speed mixer arranged in the case composed of round-bottom tank, ultrasound continuous flow chamber and means to force suspension in closed hydraulic circuit. Said mixer and said chamber are communicated via pipelines.
EFFECT: stable sedimentation suspension containing high-dispersion particles.
