Single-crystal growth and properties of CrB, Cr3B4, Cr2B3 and CrB2 from high-temperature aluminum solutions

Single crystal growth of using a high-temperature image furnace

“…Borides in general possess very high melting points and so the crystal growth of these materials by conventional techniques poses problems. CrB 2 has a melting point of around 2200 C: Single crystals of the transition metal diborides such as CrB 2 have been grown in the past by the Al flux method [2]. The flux grown crystals are in general small, precluding their use in many investigations where large volumes are required.…”

Synthesis and Investigation of Large Crystals of (Cr1−xTMx)3B4 with TM=Ti, V, Nb, Ta, Mo, and W

“…Earlier, we performed the synthesis and structure analysis of Cr B ; single crystals were obtained by the molten metal #ux method using aluminum as solvent (1,2). In our previous work, we also attempted to grow single crystals of ternary compounds (Cr \V ¹M V ) B (¹M"Ti, V, Nb, Ta, Mo, W) and to determine the ordering of the metal atoms in (Cr \V W V ) B using single-crystal X-ray di!ractometry (3).…”

Preparation of borides in Nb–B and Cr–B systems by combustion synthesis involving borothermic reduction of Nb2O5 and Cr2O3

“…Among them, NbB 2 is promising for high-temperature structural applications [5] and has been recognized as a superconductor [6,7]. CrB 2 shows potential not only as a high-temperature structural material [3], but also as a hard coating or a protective layer on tools and materials exposed to wear and corrosion [8,9].…”

“…Borides of the transition metals are very attractive materials, due to a unique combination of favorable properties like high melting point, high hardness, high mechanical strength, high electrical conductivity, good chemical stability, and excellent wear and corrosion resistance [1][2][3]. Most transition metal borides feature many stoichiometric compositions.…”
