crystal
A solid (mineral quartz or otherwise) composed of an array of atoms possessing long-range order and arranged in a pattern which is periodic in three dimensions
A fine type of glassware, or the material used to make it
{n} a transparent stone, regular form of salt or other substance made from a solution by evaporation
A regular three-dimensional form of a mineral with flat surfaces (faces) and specific angles between the faces The crystal form is an outward expression of the molecular structure of the mineral
Glasses and other containers made of crystal are referred to as crystal. Get out your best china and crystal. Any solid material whose atoms are arranged in a definite pattern and whose surface regularity reflects its internal symmetry. Each of a crystal's millions of individual structural units (unit cells) contains all the substance's atoms, molecules, or ions in the same proportions as in its chemical formula (see formula weight). The cells are repeated in all directions to form a geometric pattern, manifested by the number and orientation of external planes (crystal faces). Crystals are classified into seven crystallographic systems based on their symmetry: isometric, trigonal, hexagonal, tetragonal, orthorhombic, monoclinic, and triclinic. Crystals are generally formed when a liquid solidifies, a vapour becomes supersaturated (see saturation), or a liquid solution can no longer retain dissolved material, which is then precipitated. Metals, alloys, minerals, and semiconductors are all crystalline, at least microscopically. (A noncrystalline solid is called amorphous.) Under special conditions, a single crystal can grow to a substantial size; examples include gemstones and some artificial crystals. Few crystals are perfect; defects affect the material's electrical behaviour and may weaken or strengthen it. See also liquid crystal. Crystal Night crystal lattice Crystal Palace liquid crystal liquid crystal display rock crystal
Anything resembling crystal, as clear water, etc
a rock formed by the solidification of a substance; has regularly repeating internal structure; external plane faces
In biology refers to large, regular assembly of macromolecules such as proteins and nucleic acids It is possible to isolate and purify proteins or DNA in large quantity and let them crystallize in saturated solution These protein or DNA crystals contain millions of regularly aligned units that allow the determination of the electron distribution from X-ray diffraction studies Since atoms are distinguished by their specific numbers of electrons, their distribution allows an analysis of the atomic composition of proteins or DNA This electron distribution is then used to calculate the so called high resolution structure of molecules
A crystal is the solid form of a substance in which the atoms or molecules are arranged in a definite, repeating pattern The formation results in one of three ways: a liquid may cool or freeze into a solid; dissolved matter may precipitate out of a solution; or gases may condense into a solid form The external shape of the crystal -- smooth, symmetrically arranged, flat surfaces -- reflects its atomic structure
refers to transparent or translucent opal where the colours are sharp and visible below the surface
As in a 'crystal ball marble ' It is a clear glass marble, void of color Once manufactured with some amounts of lead to increase clarity However, EPA regulations now forbid the manufacture of glass using lead in the United States
the piezoelectric element(s) in a stack which expands and contracts in an alternating (charged) electrical field, thus inducing vibration nbsp; In low-powered ultrasonic cleaning tanks, crystals are sometimes bonded directly to the diaphragm (tank bottom or side wall)
In the past, glass of high degree of brilliance achieved by adding lead, or referring to cut glass Today, the term "crystal" can refer to the molten colorless glass which lies in the ceramic pot inside the furnace We also speak of "eco-kristall" A brilliant glass which does not contain lead Crystal, full and lead - Full lead crystal or crystal superieur contains 30% lead Half lead crystal contain 24% lead
colorless glass made of almost pure silica
Consisting of, or like, crystal; clear; transparent; lucid; pellucid; crystalline
a crystal is a solid particle in which the atoms, ions, or molecules are arranged in a regularly repeating, characteristic pattern or network of fixed points in space, with measurable distances between them 1
A regular repeat of molecules, usually with some sort of internal rotational symmetry Protein crystals are usually about 40- 60% solvent by weight and are thus fragile and sensitive to drying out [Robert L Campbell, Protein crystallography: Important points and definitions Dept of Biophysics and Biochemistry, Johns Hopkins Univ , US http: //biophysics med jhu edu/rlc/lect/definitions html
A solid composed of atoms, ions, or molecules arranged in a pattern that is periodic in three dimensions
It is bounded by plane surfaces, symmetrically arranged, and each species of crystal has fixed axial ratios
a solid formed by the solidification of a chemical and having a highly regular atomic structure
