Obtaining SiO2 particles in argon plasma jet

The paper presents an experimental set-up for obtaining particles in plasma jet and for obtaining SiO2 particles out of worn out chamotte rods in argon plasma jet. The dependence of particle dimensions on plasma jet velocity field and characteristics of the electrical current source is discussed. SiO2 particles with the diameter ranging from 100 to 1200 μm are obtained through parameters adjustment. The particles thus obtained are used for producing nano- micro-systems.
