Reaction Behavior of Phosphorus in CaO-SiO_2-FeO_x Low Basicity Slag

摘要

For investigating the reaction behavior of phosphorus in CaO-SiO_2-FeO_x low basicity slag, the CaO-SiO_2-FeO_x slag containing various amount of CaO particles was heated at 1623K and 1673K, respectively for 10 to 600s, and the products formed at the interface of the CaO particles and molten slag were observed by scanning electron microscopy (SEM) with energy dispersive X-ray (EDX). The research results showed that the solid solution containing P_2O_5 increased with the increasing of the heating temperature, and the formation of condensed phase was promoted by increasing the holding time and the CaO solid proportion.
