boron nitride

n
(Elements & Compounds) a white inert crystalline solid existing both in a graphite-like form and in an extremely hard diamond-like form (borazon). It is used as a refractory, high-temperature lubricant and insulator, and heat shield. Formula: BN

[77] developed an analytical model for simultaneously calculating the effects of geometric dimension on the thermal conductivity of polymer composites containing hexagonal boron nitride (h-BN).
To understand why this matters, it's important to compare and contrast the properties of boron nitride nanotubes (BNNTs) with those of carbon nanotubes (CNTs).
The team also showed that in addition to providing mechanical support, boron nitride improves the electronic properties of graphene by smoothening out fluctuations in the electronic charges.
Grades LPC and TPC are water-based boron nitride coatings that are ideal for use on surfaces that experience extreme corrosion in metal-processing environments, such as during the manufacture of aluminum, magnesium and other non-ferrous metals.
Nowadays, machining of hardened components with polycrystalline cubic boron nitride cutting tools has become increasingly common and it represents an established alternative to grinding [Tonshoff, H.K.].
In the technical literature, boron nitride powders with hexagonal crystal structure (5-7) and fluoroelastomers (6, 7) are described as suitable processing aids for polyethylenes in melt extrusion processes.
The 6-axis CNC Ewamatic line of tool grinding centers is designed for machining complex tungsten carbide, polycrystalline diamond (PCD) and polycrystalline boron nitride (PCBN), indexable inserts and rotary tooling.
Noritake lent the know-how for the cubic boron nitride (CBN) abrasive placed on a carbon-fiber-reinforced wheel that operates at 15,000 rpm.

Due to improved oxidation resistance at elevated temperatures, low coefficient of friction, and clean, white appearance, Boron Nitride is commonly used in high-temperature lubrication and mold release applications in the aluminum manufacturing value chain.
It is based on boron nitride, a graphene-like 2-D material, which was selected because of its ability to manipulate infrared light on extremely small length scales.
