FIELD: chemistry.
SUBSTANCE: separation of polydisperse particles is realised in complex plasma, in which dust component is formed from initial polydisperse powder. To create complex plasma low-temperature plasma with specified parameters is formed in discharge tube. Electric and thermal fields and particle charging are controlled by changing plasma parameters with setting parameters of selected particles. In this way, selection of particles of specified sizes and shape, their retaining in gravity field with further removal from discharge chamber are performed in complex plasma.
EFFECT: increased selectivity of separation of microparticles by sizes, as well as increased accuracy of separation with taking into account shape of microparticles.
