Yellow phosphorus is produced by mixing phosphorus ore, coke and silica in an electric furnace, which uses electric energy to heat the mixture and sublimate elemental phosphorus. In this process, silica is mainly used as a fluxing agent, to reduce the melting temperature, but can also promote the reduction of phosphate.[4]
