Nanotubes exhibiting a novel structure – boron nitride (BN) conical nanotubes whose walls consist of conical layers with their cone axis parallel to the tube axis, as opposed to ordinary nanotubes, composed of concentric cylindrical layers with their normal perpendicular to the tube axis – were ...
An experimental study has been performed to gain some insight into the correlations between the deposition conditions and the structure of boron nitride (BN) coatings that are used in ceramic-matrix composites. BN has been deposited at 700°C from BCl3-NH3-H2 mixtures on various substrates, b...
To determine which substance has a similar structure to boron nitride, we can follow these steps:1. Understanding Boron Nitride: - Boron nitride (BN) is a compound made up of boron and nitrogen atoms. It can exist in differ

Fine structures appearing in a hexagonal boron nitride (h-BN) under high pressure (7.7 GPa) and high temperature (1800° C) are examined by high-resolution transmission electron microscopy. At the edge of plate-like h-BN crystal spsheets are strongly bent to form a semispiral structure of ...
A new polymorph of lithium boron nitride, Li 3BN 2, was synthesized by slow-cooling of a mixture of Li 3N and BN from 1200 K. It has monoclinic symmetry, P2 1 c, a = 5.1502(2), b = 7.0824(2), c = 6.7908(2) Å, β = 112.956(2)°, Z = 4, D m = 1.74, D calcd =...
