Black diamond or black diamond powder is boron carbide?

Boron carbide, with the chemical formula B₄C, commonly known as black diamond, is a high-performance inorganic superhard ceramic material. It ranks among the top three hardest materials in nature, second only to diamond and cubic boron nitride, with a Mohs hardness of approximately 9.5 and a Vickers hardness exceeding 30 GPa. It appears as black, lustrous crystals, with a grayish-black powder. It is an indispensable special material in industrial and cutting-edge technology fields.
