METHOD FOR PRODUCTION OF NANODISPERSED METALS IN LIQUID PHASE Russian patent published in 2009 - IPC B22F9/14 B82B3/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to production of nanodisperesed metals in a liquid phase. One provides for passage of alternating current between electrodes immersed in a liquid phase and particles of metal being dispersed introduced into the interelectrode space. Ratio of the electrode length to the width of the spacing between the electrodes is equal to 20÷200:1. The electric current voltage and frequency are maintained at the level of 1.5-5.5 kV and 0.25-0.8 MHz accordingly. Additionally an inert gas is injected into the liquid phase in the form of bubbles sized 0.1-0.5 mm. The liquid phase is agitated due to continuous circulation of the liquid phase, particles of metal being dispersed and the inert gas within a looped circuit including the interelectrode space.

EFFECT: provision for extension of the functional capabilities of the method for production of nanodispersed metals in a liquid phase, its simplification, performance enhancement and improvement of working conditions.
