Carbothermal reduction behavior of quartz resources at elevated temperatures
Industrial silicon is a vital raw material in renewable energy sectors, such as solar photovoltaic panels and silicon-based anode materials. However, its production process is highly energy-intensive, consuming as much as 11 to 13 megawatt-hours (MWh) of electricity for every ton produced, which accounts for over 25% of the total production cost. Therefore, improving production techniques and reducing energy consumption are key focal points for future development. Research indicates that silicon sources from different regions exhibit significant differences in reactivity, directly affecting the production efficiency of industrial silicon. The Carbon-Silicon Composite Agglomerate (CSCA) technology contributes to effective resource utilization, improves temperature distribution within submerged arc furnaces, and enhances the formation rates of silicon carbide and silicon oxide. This study evaluates the reaction behavior of different silica sources under varying temperatures, carbon-silicon ratios, and particle sizes, along with calculations of activation energy. Based on the reactivity matching assessment, Q2 and Q3 quartz have been identified as ideal raw materials for industrial silicon production. The activation energies for these three quartz types are 269 kJ·mol−1, 319 kJ·mol−1, and 341 kJ·mol−1, respectively. These findings provide significant insights for the industrial silicon industry in selecting raw materials and optimizing the CSCA production process.
