Sažetak

The paper presents the results of calculations of silicon carbide content in residue samples of carbothermic reduction of SiO₂ after 6 hours. The content of SiC was calculated in two ways. The first from mass balance equations of samples and analysis of oxygen content. The second from analysis of oxygen and total carbon content. The values calculated by the two methods are similar. The total and free carbon content was determined according to procedures described in PN-EN ISO 21068-2:2010P and additional free carbon content at temperatures higher than recommended by the standard. The sum of calculated values of SiO₂ and SiC contents revealed measured excess of free carbon content.
