“…Our recent study revealed that the further doped Pd in the Mg-Ti-Ni alloy improved its cycle life greatly due to the excellent anti-corrosion performance of Pd [8,9]. In recent years, several research results were also published on the improvement of anticorrosion properties and cycle life of MgNi-based electrode alloys [10][11][12][13].…”

“…Nickel borides are promising functional materials, because of their potential high hardness, high melting point, high thermal stability, and excellent catalytic performance. − The superior properties are from Ni and B atoms that can construct abundant subunits, which contribute to form rich Ni–B compounds. − However, there are rarely reports of single phases of Ni–B compounds which have good crystallization, especially the bulk samples of Ni–B compounds. There is still a lack of data on the intrinsic properties of Ni–B compounds, such as conductivity and hardness.…”

Nickel borides are promising multifunctional materials for high hardness and excellent properties in catalysis and magnetism. However, it is still a blank of intrinsic properties in Ni−B compounds, because crystallization of the single phases of Ni−B compounds with micro-size is a challenge. In this work, single phases of Ni 2 B (I4/mcm), α-Ni 4 B 3 (Pnma), β-Ni 4 B 3 (C2/c), and NiB (Cmcm) are synthesized by high pressure and high temperature (HPHT). The results indicate that synthesizing α-Ni 4 B 3 and β-Ni 4 B 3 requires more energy than Ni 2 B and NiB. The growth process of Ni−B compounds is that Ni covers B to form Ni−B compounds under HPHT, which also makes the slight excess of B necessary. So, generating homogeneous distribution of starting materials and increasing the interdiffusion between Ni and B are two keys to synthesize well crystallized and purer samples by HPHT. This work uncovers the growth process of Ni−B compounds, which is significant to guide the synthesis of highly crystalline transition metal borides (TMBs) in the future.
