The near edge structure of cubic boron nitride

Micron, 2012
We compare the near edge structure (NES) of cubic boron nitride (cBN) measured using both electron energy loss spectroscopy (EELS) and X-ray absorption spectroscopy (XAS) with that calculated using three commonly used theoretical approaches. The boron and nitrogen K-edges collected using EELS and XAS from cBN powder were found to be nearly identical ...

Transformation of Cubic Boron Nitride to a Graphitic Form of Hexagonal Boron Nitride

Nature, 1959
R. H. WENTORF1 has reported that a fragment of borazon (synthetic cubic boron nitride) was twice heated to over 2000°C. in vacuo without change. Dr. Wentorf was kind enough to supply us with some small specimens, both black and yellow. Some of these, which gave random-rotation X-ray photographs showing them to be twins (only two nearly single crystals ...

Title: Periodic Mesoporous Hexagonal Boron Nitride at High Pressure: A Route to Cubic Boron Nitride Nanocrystals and Mesoporous Cubic Boron Nitride

ChemistrySelect, 2017
Abstract Periodic mesoporous hexagonal boron nitride was investigated as a precursor for nanoscale forms of cubic boron nitride. Cubic boron nitride (c‐BN) nanocrystals were obtained at a pressure of 14 GPa and a temperature of 1300 °C.

Grinding with Cubic Boron Nitride

1974
Beginning with a comparison of various abrasives and their mechanisms of wear, the specific problems when grinding high-speed steel with cubic boron nitride cup wheels are discussed. The necessary truing and dressing of the grinding section before the first usage is given special attention, because these preparations have an important effect on ground ...

Melting of cubic boron nitride at extreme pressures

Journal of Physics: Condensed Matter, 2012
Due to its large pressure range of stability and inert nature, cubic boron nitride has been proposed as a potential pressure standard for high pressure experiments. It is extremely refractive upon compression, although its melting temperature is not known beyond 10 GPa.

Activating deformation twinning in cubic boron nitride

Nature Materials
Deformation twinning, a phenomenon primarily documented within metallic systems, has remained essentially unexplored in covalent materials due to the formidable challenges posed by their inherent extreme hardness and brittleness. Here, by employing a five-degree-of-freedom nano-manipulation stage inside a transmission electron microscope, we reveal a ...

Preparation and characterization of cubic boron nitride and metal boron nitride films*

Surface and Interface Analysis, 1994
Abstract Boron nitride has generated much scientific interest due to the outstanding material properties of its cubic modification (c‐BN) which can be compared with those of diamond, and to its metal (M) boron nitride compounds (MBN) which have extraordinary mechanical properties such as high hardness and high elasticity.
