Question

tensile strength of diamond?

resistance to pressure (diamond container 1cm thick spherical)?

Answer 1

Diamond is transparent to opaque, optically isotropic crystalline carbon. It is the hardest naturally-occurring material known—owing to its strong covalent bonding—yet its toughness is only fair to good due to important structural weaknesses. The precise tensile strength of diamond is unknown. However, strength up to 60 GPa has been observed, and its theoretical intrinsic strength has been calculated to be between 90 and 225 GPa, depending on the crystal orientation.
