Abstract

The enrichment behavior of phosphorus in CaO-SiO2-FeOx-P2O3 slag was studied by making an investigation on the distribution of phosphorous content in the CaO-SiO2-FeOx-P2 O5 molten slag. The research results showed that the 2CaO · SiO2 solid particles existing in molten slag were the condensation sites for the phosphorus enrichment. The enrichment process of phosphorus in the molten slag can be recognized as three substeps: mass transfer of phosphorus from bulk slag to the surface of 2CaO · SiO2 particle, superficial solid solution reaction of phosphorus around the 2CaO · SiO2 particle, and diffusion of phosphorus through the product layer of 2CaO · SiO2-3CaO · P2O5 solid solution to the inner of 2CaO · SiO2 particle. Moreover, higher temperature is favorable to the phosphorous enrichment from molten bulk slag to the 2CaO · SiO2 particles.
