Structural and Chemical Analysis of Hydroxyapatite (HA)-Boron Nitride (BN) Nanocomposites Sintered Under Different Atmospheric Conditions

“…The triply degenerate asymmetric stretching modes (υ3 and υ2) of the PO 4 group (P−O bond) were observed at 1,048 and 430 cm −1 , respectively (Tsuda & Arends, 1993; Sauer et al, 1994). For structural characterization of hBN in the composites, the band observed at 1,368 cm −1 can be attributed to the characteristic adsorption of the in-plane B–N stretching mode (Ugarov et al, 1995; Ugarov et al, 1999; Lian et al, 2010). A characteristic hBN band was found for each composite material that was sintered under N 2 environment, whereas, in the case of sintering under ambient conditions, the corresponding band only appeared in the spectrum of the sample containing 10% BN.…”

Study of the boron levels in serum after implantation of different ratios nano-hexagonal boron nitride–hydroxy apatite in rat femurs

“…The weak peaks observed at 426 cm − 1 (ʋ2) and 585 cm −1 (ʋ4) are assigned to split, doubly degenerate and split, triply degenerate bending vibrations of [PO4] 3− , respectively [28,[30][31][32]. For structural characterization of hBN, the peak observed at 1368 cm −1 should be attributed to the characteristic adsorption of the in-plane B-N stretching vibration mode of hBN [33][34][35]. The characteristic peaks of both HA and hBN were also observed in the Raman spectra of HA-hBN composites (Fig.…”

High-Yield Synthesis of Cubic and Hexagonal Boron Nitride Nanoparticles by Laser Chemical Vapor Decomposition of Borazine

“…e Raman spectrum (Figure 3) consists of two characteristic bands at 803 and 1356 cm −1 , which correspond to hexagonal BN. e A 2 (805 cm −1 ) mode is near 803 cm −1 and the E 1 (1367 cm −1 ) mode is near 1356 cm −1 [22,23]. In addition, there are two broad bands at around 1000 cm −1 and 1400 cm −1 that can be assigned to cubic BN [27] with a large defect density that causes band broadening.…”

“…FTIR spectrum of the BNnanostructured material. e FTIR spectrum (Figure 4) consists of bands at 802.23 and 1367.19 cm −1 , which can also be related to hexagonal BN-nanostructured materials, and the c-BN absorption band at ∼1068 cm −1 that can be related to cubic BN-nanostructured materials [22,23,28,29]. Other bands observed in the FTIR spectrum have much lower intensity.…”

“…e application of the pulsed laser radiation for deposition of different materials is a very active area, where highpower pulsed laser radiation is used [21][22][23]. e borazine molecule (B 3 N 3 H 6 ) is isostructural and isoelectronic with benzene and has high vapor pressure, the exact 1 : 1 proportion of B : N, and three B-N bonds, all of which favor the stoichiometric synthesis of BN nanostructures [24].…”
