Correct Answer : Diamond
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. The scientists also calculated that another material, lonsdaleite (also called hexagonal diamond, since it’s made of carbon and is similar to diamond), is even stronger than w-BN and 58 percent stronger than diamond, setting a new record.
