“…The first aspect is the melting point of FeB as reported by [21] is around 57 • C higher than that evaluated by Van Rompaey et al [14] in the B-Fe binary system. It should be noted that the experimentally determined melting point for FeB differ greatly, from 1540 • C reported by Voroshnin et al [33] and 1590 • C by Sidorenko et al [34] to 1650 • C reported by Portnoi et al [35]. The second aspect is related to the broadness of the liquid + (Co,Fe)B two phase field.…”

“…For several decades, two phases, Fe 2 B and FeB, are mainly reported in the Fe-B system under ambient pressure. 24 Although the experimental synthesis of AlB 2 -type FeB 2 has been reported, 25 its reproduction is yet to be achieved. The CrB 4 -type FeB 4 was once theoretically considered to be unstable because of its high electron count.…”

An oP10-FeB4 phase [H. Gou, et al., Phys. Rev. Lett., 2013, 111, 157002] was recently synthesized based on previous theoretical predictions. In this study, a high-pressure phase of FeB4 (tP10-FeB4) was proposed through first-principles calculations. The tP10-FeB4 structure, which contains two formula units per unit cell, belongs to tetragonal symmetry with the space group P42/nmc. The boron atoms in tP10-FeB4 are present as tetrahedron configurations. Enthalpies as a function of pressure indicate that this new phase is probable to achieve through a phase transition from the oP10-FeB4 phase above ∼65.9 GPa. The softening of acoustic phonon at T points in the Brillouin zone may be the driving force behind the phase transition. Further analyses reveal that the tP10-FeB4 phase is a potential superhard semiconductor.

Discovery of a Superhard Iron Tetraboride Superconductor

Single crystals of novel orthorhombic (space group Pnnm) iron tetraboride FeB4 were synthesized at pressures above 8 GPa and high temperatures. Magnetic susceptibility and heat capacity measurements demonstrate bulk superconductivity below 2.9 K. The putative isotope effect on the superconducting critical temperature and the analysis of specific heat data indicate that the superconductivity in FeB4 is likely phonon mediated, which is rare for Fe-based superconductors. The discovered iron tetraboride is highly incompressible and has the nanoindentation hardness of 62(5) GPa; thus, it opens a new class of highly desirable materials combining advanced mechanical properties and superconductivity.
