FIELD: entrapping particles of extremely fine powders. SUBSTANCE: cylindrical precipitation electrode made of dielectric material is covered with thin layer of semiconducting material so as to catch particles of metals and dielectric materials finely dispersed to 20 nm within precipitator effective range. EFFECT: facilitated entrapping of very fine particles. 1 dwg
