The Application of Plasma Processes during the Production of Pigments

Abstract

The article describes the application of plasma in the production of industrial pigments. Plasmatrons, or cooled electrodes, have found practical use in chemical, petrochemical, metallurgical, and other industries. Plasma-chemical methods with the use of plasmatrons have found application in the yielding of high-quality pigments, e.g. titanium dioxide. The disadvantage of the application of plasmatrons is the dilution of the outgoing chlorine with inert gases, which reduces the service life of plasmatrons. The disadvantage can be eliminated by substituting high frequency induction plasma with arc plasma.
