Synthesis of Microparticles With Narrow Size Distribution in the Plasma of Arc and Radio-Frequency Discharges

Today, the technologies used to produce monodisperse microparticles are very expensive. Due to the wide application of monodisperse/small-dispersed microparticles in various areas of industries, their high cost, and in order to contribute to the decrease in their prime cost, we have developed a new method of production of the small-dispersed/monodisperse microparticles in the plasma of the combined radio-frequency (RF) and (dc/ac) arc discharges. The advantage of the proposed method is the production of the small-dispersed/monodisperse microparticles in the range of 1-50 μm. The dispersivity and the average size (diameter) of the small-dispersed microparticles are easily controlled by varying the parameters of the RF discharge.
