INTERACTION OF TRICALCIUM PHOSPHATE WITH PRODUCTS OF CARBOTHERMIC REDUCTION OF SILICON OXIDE.

The article presents the research results on the interaction of tricalcium phosphate with the products of carbothermic 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 gaseous phosphorus from Ca3(PO4)2, silicon-containing reducing agents form a decreasing series: (SiOg, Si)>SiC>FeSi2>FeSi.
