“…The precursor, graphitic (g-BC 3 ) was prepared by a high-pressure thermal chemical vapor deposition (HPCVD) method using C 2 H 2 , BCl 3 (as carbon and boron sources) and H 2 (30 mbar, 1225° C) 24 . A symmetrical DAC equipped with a pair of type I brilliant-cut diamond anvils (with 350 µm culets) was used in the experiment.…”

Abstract. We synthesized a cubic BC 3 (c-BC 3 ) phase, by direct transformation from graphitic phases at a pressure of 39 GPa and temperature of 2200 K in a laser-heated diamond anvil cell (DAC). A combination of x-ray diffraction (XRD), electron diffraction (ED), transmission electron microscopy (TEM) imaging, and electron energy loss spectroscopy (EELS) measurements lead us to conclude that the obtained phase is hetero-nano-diamond, c-BC 3 . Highresolution TEM (HRTEM) imaging of the c-BC 3 specimen recovered at ambient conditions demonstrates that the c-BC 3 is a single, uniform, nanocrystalline phase with a grain size of about 3-5 nm. The EELS measurements show that the atoms inside the cubic structure are bonded by sp 3 bonds. The zero-pressure lattice parameter of the c-BC 3 calculated from diffraction peaks was found to be a = 3.589 ± 0.007 Å. The composition of the c-BC 3 is determined from EELS measurements. The ratio of carbon to boron, C/B, is approximately 3 (2.8 ± 0.7).2

“…A number of graphitelike B-C phases of different stoichiometry (so called boron-substituted graphites with boron content up to 50 at%) have been synthesized by thermal chemical vapor deposition [8]. These materials should be perfect precursors for diamondlike B-C phases; however, their high-pressure, high-temperature behavior has not been well understood so far.…”

“…This is similar to the research findings of Radovic et al 33) The inhibitory effect does not become stronger as the concentration is increased, and the promoting or inhibiting of the B 2 O 3 catalytic effect depends on the combined effects of boron content, distribution and carbon materials properties and the reaction condition. 34) …”
