Abstract: Boron carbide, which has a high melting point, outstanding hardness, good mechanical properties, low specific weight, great resistance to chemical agents and high neutron absorption cross-section (10BxC, x>4) is currently used in high-technology industries—fast-breeders, lightweight armors and high-temperature thermoelectric conversion.
The contents of this review are: (1) introduction; (2) preparations—industrial preparative routes, powders, sintering (additives, pressureless, hot pressing, HIP); laboratory methods of synthesis (CVD, PVD, plasma, crystal growth); (3) analytical characterization; (4) phase diagram—a peritectic, nearly pure boron, and a wide phase homogeneity range (B4C-B10·5C); (5) rhombohedral crystal structure—a comprehensive model of the whole solid solution is proposed; (6) chemical properties; (7) physical properties—density, mechanical (strength, hardness, toughness) and thermo-electrical properties; (8) main industrial applications; (9) conclusion.

Thermodynamic consideration and ground-state search of icosahedral boron subselenide B 12 ( B 1 − x Se x ) 2 from a first-principles cluster expansion
TL;DR: In this article, the phase stability of icosahedral boron subselenide was investigated using a first-principles cluster expansion, and the results showed that, instead of a continuous solid solution, the compound is thermodynamically stable as an individual line compound at the composition of a hexagonal conventional unit cell.
