High purity graphite has the following properties due to its structure: 1), High-temperature resistance
Bond length can be determined between different elements in molecules by using the atomic radii of the atoms. Carbon bonds with itself to form two covalent network solids. Diamond's C-C bond has a distance of Sqrt[3]a/4 ≈ 0.154 nm away from each carbon since adiamond ≈ 0.357 nm, while graphite's C-C bond has a distance of a/Sqrt[3] ≈ 0.142 nm away from each carbon since agraphite ≈ 0.246 nm. Although both bonds are between the same pair of elements they can ha… WebAug 30, 2024 · The distance between the two layers is longer than the distance between carbon atoms within each layer. Hence, we can say that due to the more compact structure, diamonds have a higher density than graphite. ...
