Material: boron carbide (plate)

Boron carbide (chemical formula approximately B₄C) is an extremely hard ceramic material used in tank armor, bulletproof vests, and numerous industrial applications. With a hardness of 9.3 on the mohs scale, it is one of the hardest materials known, behind cubic boron nitride and diamond.

Boiling point	3500 °C, 3773 K, 6332 °F
Solubility in water	insoluble
Acidity (pK_a)	6-7 (20 °C)

Boron carbide is known as a robust material having high hardness, high cross section for absorption of neutrons (i.e. good shielding properties against neutrons), stability to ionizing radiation and most chemicals. Its Vickers hardness (38 GPa) and fracture toughness (3.5 MPa·m^1/2) approach the corresponding values for diamond (115 GPa and 5.3 MPa·m^1/2).
