Thermodynamic Modeling of the Impact of Impurities and NaCl Additives on the Chemical Composition of Silicon Carbide Synthesis Products by the Acheson Method

The formation of compounds that include the impurities typical of the raw materials used in the Acheson process is studied using thermodynamic modeling. It is shown that the yield of silicon carbide in the Acheson process is significantly influenced by moisture and sulfur content in the coke. The sequence of gasification of elements from the reaction mixture during heating was determined. It is shown that sodium chloride significantly affects the state of metallic impurities facilitating gasification of aluminum, magnesium and calcium. The amount of volatile silicon chloride formed in the presence of sodium chloride was estimated.

期刊介绍： Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
