  • Process for hydrogenating silicon tetrachloride
    Patent number: 11027979
    Abstract: The invention relates to a process for hydrogenating silicon tetrachloride in a reactor, wherein a reactant gas containing hydrogen and silicon tetrachloride is heated to a temperature between 850° C. and 1600° C. by means of at least one heating element, which comprises a graphite surface, wherein the temperature of the heating element is between 850° C. and 1600° C. The process is characterized in that a nitrogen compound is added to the reactant gas in a substance amount fraction of 0.1 to 10% based on hydrogen.
