Non-crystalline Materials – Definition - Material Properties
WebCrystal 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 unit cell is defined as a parallelepiped, providing six lattice parameters taken as the lengths of the cell edges (a, b, c) and the angles … Web15.2.2 Definition and Basic Concept of Nanoglass.
