Расчет равновесных составов систем Si – O – C и Si – O – C – H проводился «константным» методом с использованием программы компьютерного моделирования высокотемпературных химических взаимодействий PLASMA. Установлено, что в обеих системах процесс карбидообразования является доминирующим. При стехиометрическом составе шихты максимальное содержание в продуктах восстановления карбида кремния достигается при температуре 1700 К, а при 10 %-м недостатке углерода – при 1900 К. Введение в систему водорода фактически не влияет на процесс карбидообразования, что обусловлено низким (менее 0,001 моль) содержанием углеводородов и углеводородных радикалов в газовой фазе при температурах карбидообразования. В системе Si – O – C равновесная степень превращения кремния в карбид не превышает 0,97, что соответствует содержанию монооксида кремния в газовой фазе 0,02 моль, вследствие чего из шихты стехиометрического состава (SiO2 + 3C) получить однофазный, не содержащий свободный углерод, карбид кремния невозможно. Этого можно избежать при использовании шихты с некоторым (примерно 10 %) недостатком углерода-восстановителя.</p></abstract><trans-abstract xml:lang="en"><p>Thermodynamic modeling of high-temperature interactions of microsilica and brown-coal semi-coke was carried out. Calculation of equilibrium structures of Si – O – C and Si – O – C – H systems was defi ned by a “constant” method with the use of the computer modeling program of high-temperature chemical interactions of “PLASMA”. It was established that in both systems the formation process of carbide was dominating. At stoichiometric composition of furnace charge the maximum contents in products of restoration of silicon carbide can be reached at 1700 K, and at 10 % a lack of carbon – 1900 K. The introduction of hydrogen to system doesn’t actually infl uence on the process of carbide formation that is caused by low (less than 0,001 mol) contents in a gas phase at temperatures of carbide formation of hydrocarbons and hydrocarbonic radicals. In Si – O – C system the equilibrium extent of transformation of silicon into carbide doesn’t exceed 0,97, that corresponds to the content of monoxide of silicon in a gas phase of 0,02 mol, owing to what from furnace charge of stoichiometric structure (SiO2 + 3C) it is impossible to receive the single-phase, not containing free carbon, carbide of silicon. It can be avoided using furnace charge with some (~ 10 %) lack of carbon reducer.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кремнезем</kwd><kwd>буроугольный полукокс</kwd><kwd>термодинамическое моделирование</kwd><kwd>«константный» метод</kwd><kwd>карбид кремния</kwd></kwd-group><kwd-group xml:lang="en"><kwd>silica</kwd><kwd>brown-coal semi-coke</kwd><kwd>thermodynamic modeling</kwd><kwd>«constant » method</kwd><kwd>silicon carbide</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Galevskii G.V., Protopopov E.V., Temlyantsev M.V.
