- Heterodiamond
Heterodiamond is a
superhard material containingboron ,carbon , andnitrogen (BCN). It is formed in high temperatures and high pressures, eg. by application of an explosiveshock wave to a mixture ofdiamond andcubic boron nitride . A 2002 synthesis documented heterodiamond withVickers hardness ranging from 41 to 68gigapascal s, compared to 70 to 100 for diamond. [patent|US|6759128]References
