摘要

The electrical resistivity of the following solid carbon-based reducing agents is compared: charcoal, petroleum coke, rexil special coke, KhMI special coke (developed at Abishev Chemical and Metallurgical Institute, Karaganda), and blast furnace coke. The goal is to better understand the factors affecting the performance of carbon-based reducing agents in electrofurnace heating. At the temperature used in electrofurnace production of technical-grade silicon (~1600°C), rexil produced from long-flame Shubarkol coal has the greatest electrical resistivity.
