Graphite crystal lattice
WebIt is the arrangement of atoms or molecules in a given substance that defines the crystal faces of that substance. It is the relation of these faces to the crystallographic axes that defines to which crystal system a substance belongs. Graphite crystallizes in the hexagonal system. Four crystallographic axes define the hexagonal system. WebA crystal is a well-ordered arrangement of atoms that can best be pictured as spheres touching one another. They are ordered in planes, called lattices, which penetrate one another in specific ways. For iron, the lattice arrangement… Read More metal hydrides In hydrogen: Reactivity of hydrogen

Natural graphite is mostly used for refractories, batteries, steelmaking, expanded graphite, brake linings, foundry facings, and lubricants. The use of graphite as a refractory (heat-resistant) material began before 1900 with graphite crucibles used to hold molten metal; this is now a minor part of refractories. In the mid-1980s, the carbon-magnesite brick became important, …
