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. WebThe rigid network of carbon atoms, held together by strong covalent bonds, makes diamond very hard. This makes it useful for cutting tools, such as diamond-tipped glass cutters and oil rig drills. Graphite Structure and bonding. Graphite is a giant covalent substance in which: each carbon atom is joined to three other carbon atoms by covalent bonds

WebThe sole reason for graphite being softer than a diamond is the difference in their crystal structures. Graphite is a crystalline form of carbon that has carbon atoms ordered in a hexagonal structure making it extremely soft. On the other hand, diamond features a tetrahedral crystal structure which gives it its unparalleled hardness.
