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.
Highlights
Plasma is an ionized gas containing charged particles, i.e. unbound electrons and ions
Any substance at sufficiently high temperatures, as well as high-density gases transform into a plasma state
The higher the ionization energy, the higher temperatures are required for ionization
Summary
Plasma is an ionized gas containing charged particles, i.e. unbound electrons and ions. There exist various areas of application of plasma processes: in chemical industry for producing polymers [1, 2], removing corrosion layers [3], residuals [4], powders [5, 6], deposition of films and membranes [7, 8, 9], separation of isotopes [10], obtaining metals and metal oxides [11, 12, 13, 14, 15, 16, 17], biotechnology [18], microbiology, medical technology [19], geophysics [20], textile industry [21]. One of the most challenging trends of civil engineering is the production of pigments used as paints as coatings
