In materials science, a single crystal (or single-crystal solid or monocrystalline solid) is a material in which the crystal lattice of the entire sample is continuous and unbroken to the edges of the sample, with no grain boundaries.
Glass primarily consists of silica (SiO 2), also known as silicon dioxide. This forms the backbone of the glass structure. Other essential components include sodium oxide (Na 2 O) and calcium oxide (CaO), which act as fluxes, lowering the melting point of silica to make it easier to work with.
Single crystals have infinite periodicity, polycrystals have local periodicity, and amorphous solids (and liquids) have no long-range order. An ideal single crystal has an atomic structure that repeats periodically across its whole volume.
An ideal single crystal has an atomic structure that repeats periodically across its whole volume. Even at infinite length scales, each atom is related to every other equivalent atom in the structure by translational symmetry. A polycrystalline solid or polycrystal is comprised of many individual grains or crystallites.
