Yakubu Francisco Yakubu

Hello Mr Osanyinpeju,

1) Fullerite: an ultra-hard material with hardness ranging from 150 to 310 GPa. Diamond has hardness ranging from 150 to 167 GPa. It is still not possible to industrially manufacture fullerite due to the high pressures and temperatures required.

2) Wurtzite boron nitride. It is also worth researching.

Regards,

Yakubu
