Transition metal diborides in hexagonal AlB2 type structure typically form stable MB2 phases for group IV elements (M = Ti, Zr, Hf). For group V (M = V, Nb, Ta) and group VI (M = Cr, Mo, W) the stability is reduced and an alternative rhombohedral MB2 structure becomes more stable. In this work we investigate the effect of vacancies on the B-site in hexagonal MB2 and its influence on the phase stability and the structure for 2

“…The electrical resistivities of the crystals were measured by a direct-current four-probe technique at room temperature in air. In our previous work, ternary VAlB, NbAlB, and TaAlB phases of the UBC-type structure were not obtained from the single crystal growth experiment in the V-Al-B, Nb-Al-B, and Ta-Al-B systems using the same crystal growth method (6)(7)(8)(9). EDX and chemical analyses show that the compositions of the obtained MoAlB crystals in the Va elements-Mo-Al-B systems are close to the MoAlB composition (Table 3).…”

“…In addition, in the W-Al-B system, it has been found that single crystals of a new compound WAlB (space group Cmcm) (3) and of the earlier known MoAlB can be grown by using the aluminium solution technique (4). Single crystal growth experiments have been performed in the Cr-Al-B and Va group (transition elements)-Al-B systems, however, ternary boride CrAlB, VAlB, NbAlB, and TaAlB phases were not reported (5)(6)(7)(8)(9). In previous work, we performed the preparation and structure analysis for the single crystals of MoAlB (4), WAlB (3), and Cr \6 Mo 6 AlB (X"0.39) (10).…”

“…For the V 5 B 6(ortho) structural type, zig-zag boron chains exist parallel to the boron double chains. [139,145,157] In addition, these double chains can be considered as primitive elements of hexagonal unit cells, characteristic of AlB 2(hex) .…”

Rediscovering the Crystal Chemistry of Borides

2017

For decades, borides have been primarily studied as crystallographic oddities. With such a wide variety of structures (a quick survey of the Inorganic Crystal Structure Database counts 1253 entries for binary boron compounds!), it is surprising that the applications of borides have been quite limited despite a great deal of fundamental research. If anything, the rich crystal chemistry found in borides could well provide the right tool for almost any application. The interplay between metals and the boron results in even more varied material's properties, many of which can be tuned via chemistry. Thus, the aim of this review is to reintroduce to the scientific community the developments in boride crystal chemistry over the past 60 years. We tie structures to material properties, and furthermore, elaborate on convenient synthetic routes toward preparing borides.
