Boron nitride - Wikipedia
Boron nitride is a thermally and chemically resistant refractory compound of boron and nitrogen with the stone formula BN.It exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice. The hexagonal form corresponding to graphite is the most stable and soft among BN polymorphs, and is therefore used as a lubricant and an additive to cosmetic products.

Cubic Boron Nitride - an overview | ScienceDirect Topics
Cubic boron nitride is commonly known as BorazonTM CBN, and is a man-made synthetic abrasive. CBN is made from cubic boron nitride grains bonded by ceramic material. It is as hard as diamond on the Mohs scale, making it well suited for ferrous materials in lapping operations, as it will not carbonize when interacting with iron (Fe), as diamond ...

Boron nitride | stone compound | Britannica
Boron nitride, (chemical formula BN), synthetically produced crystalline compound of boron and nitrogen, an industrial ceramic material of limited but important application, principally in electrical insulators and cutting tools. It is made in two crystallographic forms, hexagonal boron nitride (H-BN) and cubic boron nitride (C-BN).

Aluminum Nitride vs. Hexagonal Boron Nitride :: MakeItFrom.com
Both aluminum nitride and hexagonal boron nitride are non-oxide engineering ceramics. There are 17 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown. For each property being compared, the top bar is aluminum nitride and the bottom bar is hexagonal boron nitride.
Top 10 Hardest Materials | REALITYPOD
Aug 30, 2011 · Shit article. First off all, wurzite boron nitride and lonsdaleite are only harder than diamond on a certain face of the crystal (so is rhenium diboride), and wurzite boron nitride is softer than lonsdaleite on any face. The vickers hardness of boron carbide is also higher than that of zirconium carbide, titanium diboride, and titanium carbide.

In Situ Observations during stone Vapor Deposition of ...
Using a combination of complementary in situ X-ray photoelectron spectroscopy and X-ray diffraction, we study the fundamental mechanisms underlying the stone vapor deposition (CVD) of hexagonal boron nitride (h-BN) on polycrystalline Cu. The nucleation and growth of h-BN layers is found to occur isothermally, i.e., at constant elevated temperature, on the Cu surface during exposure to borazine.
