FIELD: metallurgy.
SUBSTANCE: during technical silicium manufacturing the furnace-charge is used, it contains quartzite, charcoal, oil coke, coal, wood chips, and silicone carbide on nitride binding in the following composition in wt %: quartzite - 42.7-50.3; charcoal - 2.7-5.1; oil coke - 1.6-3.0; coal - 13.3-24.9; wood chips - 6.1-10.4; silicone carbide on nitride binding - 6.2-33.5. The silicon-carbide plates can be used as silicone carbide on nitride binding, the plates are used for bath lining of the electrolysers for aluminium manufacturing.
EFFECT: reduced losses of the manufactured silicium due to decreasing of the monoxide generated during casting, resulting in reduced feed stock and process energy consumption.
