2020年11月1日 · X-ray diffraction (XRD) patterns were collected using a Bruker D8 diffractometer (Bruker Co., Karlsruhe, Germany). XRD samples were prepared by suspending a small amount of powder in ethanol on a zero-background holder and drying with the goal of obtaining a thin layer of randomly-oriented particles.

2019年2月20日 · Here, we report dense bulk hBN with 97.6% theoretical density achieved at a lower preparation temperature (1700 °C) via a self-densifying mechanism without sintering additives.

Figure 2 a shows the X-ray diffraction (XRD) spectra of the bulk hBN, plasma-treated hBN (p-hBN), calcined hBN (c-hBN), and calcined and plasma-treated hBN (p-c-hBN). All the XRD...

2023年9月20日 · In this work, 2D-hBN ultrathin nanosheets have been prepared by hydrothermal method at an optimum temperature. The well-prepared 2D-hBN was characterized by Transmission electron microscope (TEM), X-Ray Diffraction (XRD), and UV–Visible absorption spectroscopy (UV–Vis).

Fourier Transform Infrared Spectrometer (FTIR), which has been widely used for BN characterization, can also be applied for differentiating the crystal orientation of h-BN by...

6、 x射线衍射 （xrd）： 为了研究c-BN的相变温度和微观结构变化，对c-BN粉末进行了热处理（1450℃-1850 °C）来确定合适的烧结温度。 从图6中可以看出，在1450℃热处理后，c-BN的衍射峰没有变化，而h-BN的（002）衍射峰在1550°C热处理后开始出现 。

2021年1月17日 · 其中包含石墨烯、六方氮化硼（h-BN）、二硫化钼等TMDs的拉曼（Raman）、光致发光（PL）、XRD、带隙、 晶格结构 、 载流子迁移率 及热导率热膨胀系数等参数，以供大家参考，表中数据均来源于文献，如有不准确之处，希望大家指出：

2019年7月1日 · Hexagonal boron nitride (hBN) is an ultra-wide bandgap insulating material, which possesses a graphite-like layered structure, and the two-dimensional (2D) hexagonal boron nitride nanosheets (hBNNS), exfoliated from the bulk hBN, have promising applications in electronic packaging and high-power devices, due to the high thermal conductivity ...

The hBN nanoplatelets obtained from the bulk hBN were characterized using various analytical techniques such as x-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared...

In this work, we demonstrate, for the first time, a readily available and practical method of quantifying h-BN sheet content in BNNT samples. The technique is demonstrated after utilizing two different BNNT enrichment methods, surfactant wrapping and centrifugation, and sonication-assisted isovolumetric filtration.
