High-temperature Reactions in the System Titanium Carbide—Boron Carbide¹

Thermodynamic assessment of the Ti–B system

“…Ti 2 B 5 [15,22,25,26], TiB x (TiB 10 or TiB 12 ) [27] and Ti 2 B [25] were also reported but none of them were detected by the same investigation at one time. Furthermore, later researchers [8,9] did not observe those phases.…”

Mixed Interstitial Compounds

“…The hard and stable boron carbide, B 4 C, enters upon boron excess, as the alternative to graphite; it equilibrates with TiB 2 rather than with the carbide 19 . There is hardly any intersolubility, and the stable coexistence of the nearpure carbide and borides is a dominant feature.…”

Synthesis of candidate advanced technology fuel: Uranium diboride (UB2) via carbo/borothermic reduction of UO2

“…In particular, it would be highly desirable to use uranium dioxide as a precursor owing to the wealth of industrial experience and wellestablished techniques regarding its preparation and handling. Past work has used B 2 O 3 or B 4 C with an oxide that is then reduced at elevated temperatures forming the desired boride phase [37,38,39,40,41].…”
