§ 499 GPa is for the c-axis direction; E = 403 GPa perpendicular to the c-axis [5]. Figure 4 displays the results of the NanoBlitz test on CoorsTek TTZ, with the derived Young’s modulus and hardness.

Natural diamonds have a hardness of nearly 150 GPa, but ultrahard fullerite has surpassed diamond to become first on the list of hardest materials with values that range from 150 to 300 GPa. All ...

§ Measured at a wavelength of 633 nm. † Measured at 1 MHz. These were measured with respect to Young’s modulus and hardness using the iNano. A Berkowich indenter was used (as is common) to produce the ...

In its hard state, it achieves a hardness of 86.5 Shore D (comparable to hard plastics), a compression strength of 81.7 MPa, and a Young's modulus of 1.2 GPa—significantly surpassing current 3D ...
