The energy of absolutely free-standing chemically vapour-deposited diamond was resolute employing a bursting-disc exam, A 3-place bend take a look at and also a 4-position bend exam. The bursting-disc approach has positive aspects for pinpointing the toughness of ceramic elements due to the fact the most tensile stress is with the centre in the disc. The A lot smaller stresses close to the sample edges are hardly ever liable for failure and so edge effects are negligible. Nonetheless, the bursting-disc test is commonly impractical for ascertaining the power of chemically vapour-deposited diamond since the expense of samples is high. A 3-point bend exam is usually used rather, given that it might be carried out on smaller samples. On the other hand, the region stressed within the three-point bend take a look at is scaled-down, and so There's significantly less prospect of stressing a significant flaw, leading to better strength values.

Identical observations ended up produced regarding the existence of the C–O bond in this sample established likewise. The chemical bonds shaped by compact amounts of nitrogen or oxygen with carbon is usually calculated working with initial concepts dependant on density practical principle (DFT) [twenty].
