Sažetak

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