FAQ
Frequently Asked Questions
While extremely rare natural occurrences have been reported, boron nitride is overwhelmingly a synthetically produced industrial material.
Hexagonal boron nitride (h-BN) has a layered, lubricious structure similar to graphite and is a thermal conductor but electrical insulator. Cubic boron nitride (c-BN) has a diamond-like structure, is ultra-hard, and is used primarily as an abrasive.
Hexagonal boron nitride is an excellent electrical insulator. Cubic boron nitride is also an insulator, though some doped or specific forms can exhibit semiconducting properties.
Hexagonal boron nitride is called 'white graphite' because its microcrystalline structure and lubricious properties are visually and functionally analogous to graphite, but it is white in colour and electrically insulating.
A binary compound of boron and nitrogen, known for its extreme hardness and high thermal conductivity.
Boron nitride is usually technical / scientific in register.
Boron nitride: in British English it is pronounced /ˌbɔː.rɒn ˈnaɪ.traɪd/, and in American English it is pronounced /ˌbɔːr.ɑːn ˈnaɪ.traɪd/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think 'Boron' + 'Nitride' as a 'Bionic Armour' – it's an incredibly tough, synthetic armour for tools.
Conceptual Metaphor
INVISIBLE ARMOUR (for coatings), WHITE GRAPHITE (for lubricious h-BN), SYNTHETIC DIAMOND (for hard c-BN).
