The article presents the research results on the interaction of tricalcium phosphate with the products of carbother-mic reduction of silicon oxide (SiOg, SiC, iron silicides). The research was carried out by computer thermodynamic modeling using the HSC-6.0 software package. It was established that SiOg, Si, and SiC are highly reactive towards tricalcium phosphate at relatively low temperatures. It was found that, according to the formation degree of gase-ous phosphorus from Ca3 (PO4)2, silicon-containing reducing agents form a decreasing series: (SiOg, Si)>SiC>FeSi2 >FeSi.
