The formation and oxidation of BC3, a new graphitelike material

Structural Characterization of Boron-doped Submicron Vapor-grown Carbon Fibers and Their Anode Performance

“…[9][10][11][12][13][14] Generally, it is agreed that a small number of boron atoms can enter the graphite lattice through a substitution reaction, possibly changing the microstructure of the original carbon material. 15,16 In particular, it has been reported that the use of boron-doped carbon materials as an anode material in lithium ion batteries shows good cyclic efficiency and a little higher capacity than that of undoped carbon materials.…”

Crystal structures and metastability of carbon-boron compounds C3B and C5B

“…However, it was suggested that incorporating of large amounts of boron into diamond would result in extreme enhancement of superconductivity [4]. B-doped diamond synthesized at [8][9] GPa and 2500-2800 K was reported to be a type-II superconductor with transition temperature T c = 5 K [5], while T c of the heavily B-doped diamond (~ 20 at. % of B) was predicted, assuming simple hypothetical structural models [4][5], to rise to T c = 55 K [5], prompting high pressure experiments.…”

Synthesis and oxidation behavior of boron-substituted carbon powders by hot filament chemical vapor deposition

“…Boron-substituted graphite materials, referred to as B x C 1−x (0<x<0.25), have been studied theoretically [5][6][7] and experimentally [8][9][10][11][12][13][14][15][16][17][18][19][20] . Structural and electronic properties of some ordered B x C 1−x compounds have been investigated using different calculational methods [5][6][7] .…”

“…Jones and Thrower [4] have proposed that the inhibiting effect by substitutional boron on carbon oxidation was directly proportional to the boron concentration in the compound. The B x C 1−x materials with high boron concentrations are thermodynamically metastable and can only be obtained by nonequilibrium techniques, like various chemical vapor deposition (CVD) methods [12][13][14][15][16][17][18][19] . By thermal CVD at 800℃ using benzene and boron trichloride as gas sources, Kouvetakis et al [12] obtained one novel compound BC 3 , in which the boron concentration reached 25 at.%.…”
