Crystalline structure of diamond and graphite
WebJul 19, 2024 · Why is crystal structure important? The crystal structure is just as important to the crystal as the molecules are. This becomes clear when we compare crystals made from carbon. For example, diamonds are transparent and so strong they can cut through glass. Meanwhile, graphite is dark, opaque and so soft that tiny bits of it are … WebAlthough graphite and diamond have the same chemical composition, their different crystal structures give them very different physical characteristics. For example, diamond is one of the hardest known substances, while graphite is one of the softest. Diamonds are typically clear, make excellent abrasives, and are good electrical insulators.
