- Аннотация: The main question for understanding the corrosion of a side lining made from silicon carbide based on a silicon nitride binder is whether corrosion of Si3N4–SiC material by gases (and, in particular, oxidation) is preceded by corrosion by molten electrolyte, or corrosion by molten electrolyte plays its own role in material degradation during service. It is more probable that reactions of SiC and Si 3N4 with molten cryolite pass through a pre-oxidation stage. Calculations show that the majority of possible reactions of SiC and Si3N4 with oxygen,carbon monoxide, and carbon dioxide have a positive volumetric effect, which reduces material porosity, but may cause crack development within it. In this case the silicon oxide formed is dissolved in molten electrolyte and may also react with electrolyte components in the gas phase. For citation: Yurkov A.L., Malakho A.P., Avdeev V.V.
