wurtzite boron nitride(PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world.
But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond..
Why does glass cut so easily?
Glass is hard, so your soft supple skin gets cut. The fracture surface is highly reactive and glass is prone to stress corrosion. The moisture in the air will actively blunt features on the fracture surface.
