the regular, geometric arrangement of atoms in a solid.
A substance (usually solid but can be liquid) in which the atoms or molecules are arranged in a definate pattern that is repeated regularly in three dimensions. Crystals tend to develop forms bounded by definitely oriented plane surfaces that are harmonious with their internal structure. They may belong to any of six crystal systems: cubic, hexagonal, tetragonal, orthorhombic, monoclinic, or triclinic.
(cryst'-tal-line) Having the properties of a crystal, specifically a regularly repeated long-range three dimensional internal arrangement of atoms.
In the case of polymers, a material that, on a molecular level, has regions where the polymer chains are packed closely together into an ordered or crystal lattice structure.
Imperfectly crystallized; as, granite is only crystalline, while quartz crystal is perfectly crystallized.
consisting of or containing or of the nature of crystals; "granite is crystalline"
Indicates a rock is composed of mineral crystals rather than glass. In general, when igneous melts cool very fast they form glass (like obsidian), but when they cool slower, mineral crystals have an opportunity to grow.
Glass like formation of a mineral. A diamond is a crystalline form of carbon.
