Combined Vibrational Spectroscopic and Theoretical Study on Nature ofc-BN Powders Surface

Abstract

Cubic boron nitride (c-BN) powders of different particle size fractions have been examined with FTIR, DRIFT, ATR, micro-Raman, and micro-IR spectroscopy. The heterogeneity of the c-BN surface has been shown. The quantum chemical simulations of structure and vibrational spectra of c-BN particles allowed to assign the main vibrational bands and perform structure-property correlations.

Morphology control of hexagonal boron nitride by a silane coupling agent

“…As we know, hexagonal BN has two typical FT-IR active modes: in-plane bending near to 1390 cm À 1 and out-of-plane stretching near to 780 cm À 1 . However, cubic BN has one characteristic stretching mode corresponding to an absorption near to 1080 cm À 1 [25][26][27]. As shown in Fig.…”

Thermal dependence of the properties of cubic boron nitride crystal

“…So it has amazing aspects [10] of multiuse [11,12] such as in polishing, cutting [13] and protection [14], and it has been the core for many studies [15][16][17][18] since its discovery in 1957 [19]. Methods of semiempirical calculations give a privilege of reasonable computer execution time for getting the results due to the approximations which are involved [20,21], accordingly they are used in many studies [22][23][24][25].…”
