Abstract

This article reports the results of thermodynamic modelling of the chemical interaction between iron phosphides and CaSi₂ in the systems 4CaSi₂-Fe₂P, 2CaSi₂-Fe₂P, 1,2CaSi₂- Fe₂P, 2/3СаSi₂- Fe₂P. It was established that the rate of chemical reaction between СаSi₂ and Fe₂P with the release of gaseous phosphorus increases, when the mole fraction of Fe₂P in decreased in the studied systems. The Completion of the interaction of СаSi₂ with Fe₂P is observed at Т=1500⁰С and a mole fraction of Fe₂P 20 %. The interaction of СаSi₂ with Fe₂P in the system 4СаSi₂-Fe₂P occurs stepwise to the consecutive formation of FeP₂, FeP and P₂, P₄.
