Crystallographic definition

WebX-ray crystallography is a tool used for determining the atomic and molecular structure of a crystal. The underlying principle is that the crystalline atoms cause a beam of X-rays to diffract into many specific directions (Fig. 2.10).By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a 3D picture of the density of … WebDefinition. From any point of the three-dimensional Euclidean space the symmetry operations of a given space group G generate an infinite set of points, called a crystallographic orbit.The space group G is called the generating space group of the orbit. Two crystallographic orbits are said to be configuration-equivalent if and only if their …

WebTwinning is a phenomenon somewhere between a crystallographic defect and a grain boundary. Like a grain boundary, a twin boundary has different crystal orientations on its two sides. But unlike a grain boundary, the orientations are not random, but related in a specific, mirror-image way. A twin boundary happens when the crystals on either side ...

However, in the case of a solid solution, the same phase may exist with different compositions (Cu in Al, C in Fe, etc.) and for the same composition, several phases may exist ( allotropic ... WebApr 9, 2024 · Crystallographic Planes We know that crystal lattices are the infinite array of points arranged periodically in space. These points can be joined together by drawing a straight line and by extending these lines in the three-dimension we notice that they appear to be a set of crystal planes or Crystallographic Planes. ct201830
