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 matter.. The smallest group of particles in the material that constitutes the

The Influence of Defects in the Crystal Structure on

Abstract. Machatschki (1928) correctly proposed that the feldspar structure is based on a framework of linked TO 4 tetrahedra, but Taylor (1933) took the crucial step when he envisaged the actual topology of the framework structure on Christmas Day, 1932, followed by a comprehensive survey of the structural variants (Taylor et al., 1934).
