Abstract:

This paper discusses the prospects of using the method of processing solutions by the contact non-equilibrium plasma with reduced pressure to obtain nanosized metal compounds as highly dispersed powders and colloidal dispersions on example of obtaining oxygen-containing compounds of cobalt, copper and silver compounds in water solution. The difference of this method is the ability to use very dilute solutions, also thanks to its constructive design, the process of synthesis of particles is controlled by adjusting the parameters of plasma-chemical process. It is noted that this method has undoubted advantages in terms of versatility, low power, the possibility of obtaining a size of 10-100 nm particles. A separation into fractions by separating them in the water solution after the plasma chemical treatment is possible. The ability to control the process of synthesis of particles by adjusting the parameters of plasma chemical processing, ease of control parameters of the process, possibility of obtaining particles with the division on fractions, possibility of a significant reduction in energy consumption and improve product quality in the transition to film mode allows to speak about high prospects of this method to produce ultra and nanosized metal compounds.
