Crystallization and interruption
WebCrystalline. the state of a solid material characterized by a periodic and repeating 3D array of atoms, ions or molecules. Crystal structure. For crystalline materials, the manner in which atoms or ions are spatially arranged. It is defined in terms of the unit cell geometry and the atom positions within the unit cell. Atomic hard sphere model. WebA planar defect is a discontinuity of the perfect crystal structure across a plane. Interfacial defects are boundaries that have two dimensions and normally separate regions of the materials that have different crystal structures and/or crystallographic orientations. Interfacial defects exist at an angle between any two faces of a crystal or ...
