Definition of a crystal structure
The scientific definition of a "crystal" is based on the microscopic arrangement of atoms inside it, called the crystal structure. A crystal is a solid where the atoms form a periodic arrangement. (Quasicrystals are an exception, see below). Not all solids are crystals. For example, when liquid water starts freezing, the … WebWhat is Polycrystalline Structure – Polycrystalline Materials – Definition. Not all solids are single crystals. When a metal starts with crystallization, the phase change begins with small crystals that grow until they fuse, forming a polycrystalline structure. A crystalline material is one in which the atoms are situated in a repeating or ...

Most electrons in solids are bound to the atoms in local orbits, but a small fraction of the electrons are available to move easily through the entire crystal. These so-called conduction electrons carry the electrical current.
Webcrystal, any solid material in which the component atoms are arranged in a definite pattern and whose surface regularity reflects its internal symmetry.
