Abstract:Metal borides and carbides, TiB2/TiC and ZrB2/ZrC are widely used nanostructured composite materials. A detailed thermodynamic analysis was performed to determine the formation conditions of titanium and zirconium borides and carbides in the Ti-B-O-C and Zr-B-O-C systems. The complete thermodynamic analysis was carried out in vacuum for the reactions 2TiO2 + B2O3 + 8C = TiB2 + TiC + 7CO and 2ZrO2 + B2O3 + 8C = ZrB2 + ZrC + 7СО. On the basis of the theoretically found results, experimental synthetic routes were… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
