Question

name that.... which is harder than a dimond.​

Answer 1

Answer:

Explanation:

Lonsdaleite - also called hexagonal diamond in reference to the crystal structure, is an allotrope of carbon (like the diamond) with a hexagonal lattice. In nature, it forms when meteorites containing graphite strike the Earth. Although in its natural form it is not as hard as a natural diamond, in lab conditions it does achieve a higher hardness level than a diamond by a few percents.

Wurtzite Boron Nitride - w-BN considered by scientists to be under certain circumstances harder than a diamond. This is actually the only non carbon material to achieve this hardness level. But again it is only under special circumstances.
