WebJun 7, 2024 · English: Crystal structure refers to the microscopic structure of the crystal. Should not be confused with crystal morphology, which refers to the macroscopic aspect of the crystal instead, see Category:Crystal morphologies , or with the crystallin structure, which is a water-soluble structural protein, see Category:Crystallin protein structures In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions, or molecules in a crystalline material. Ordered structures occur from the intrinsic nature of the constituent particles to form symmetric patterns that repeat along the principal directions of three-dimensional space in … See more Crystal structure is described in terms of the geometry of arrangement of particles in the unit cells. The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. The geometry of the … See more Real crystals feature defects or irregularities in the ideal arrangements described above and it is these defects that critically determine many of the electrical and mechanical properties of real materials. Impurities See more Polymorphism is the occurrence of multiple crystalline forms of a material. It is found in many crystalline materials including polymers, minerals, and metals. According to Gibbs' rules of … See more The defining property of a crystal is its inherent symmetry.
