Crystallography From Wikibooks, the open-content textbooks collection Jump to: navigation search A reader has identified this book as an undeveloped draft or outline. You can help to develop the work , or you can ask for assistance in the project room Crystallography is a branch of geometry that deals with indefinitely repeating patterns. Two-dimensional crystallography can be used, for example, to describe the way tiles cover a floor. Extending the field into three dimensions allows a general description of the way atoms or molecules arrange themselves into crystals. The three-dimensional crystallography was proven to be complete over a century ago. The fact that the mathematics itself cannot be advanced without some change of its axioms has meant that it is studied less often as pure mathematics, than as a means of understanding the details of complex structures in matter. Two fields are particularly reliant on it: materials scientist use it to describe the structure of engineering materials, often with particular attention to crystallographic defects ; biochemists use it to describe the structure of biopolymers (see proteomics for an example), which usually must be processed laboriously before they form crystals. In mathematical terms, a crystal is an object with

Search the Internet with Kids.Net.Au Encyclopedia > Crystallography Article Content Crystallography Crystallography most often refers to the experimental methods used to determine the arrangement of atoms in solids. More traditionally, it is the scientific study of crystals. Crystallographic methods all rely on the analysis of the diffraction patterns that emerge from a sample that is targetted by a beam of some type. The beam is not always electromagnetic radiation , even though X-rays are the most common choice. For some purposes electrons or neutrons are used, which is possible due to the wave properties of particles that are described by quantum mechanics . Crystallographers often explicitly state the type of illumination used when refering to a method, as with the terms X-ray diffraction, neutron diffraction and electron diffraction. Crystallography by itself typically implies X-rays. Crystallography is used to generate a kind of image of how the atoms in a material are arranged. The most familiar way to generate an image is with a lens , such as the lenses that a microscope uses to image the fine features of a sample. But the wavelengths of radiation employed by microscopes are long compared both to

Crystallography and Minerals Arranged by Crystal Form The Crystallography section in the Mineralogy Database is moving to a new, permanent domain. Please make sure to bookmark the new location at http://webmineral.com/crystall.shtml Crystal Groups and Classes - Crystallography groups are composed of 32 classes of symmetry derived from observations of the external crystal form. From these 32 classes, 230 space groups (see Crystallography 101 ) are distinguishable using x-ray analysis. For additional information on crystal systems, please review an excellent on-line treatment of this subject, the Introduction to Crystallography and Mineral Crystal Systems by Mike and Darcy Howard. Example Crystal Morphology - To further illustrate these symmetry elements, the example crystalline forms for each symmetry class were constructed using Faces (version 3.5) by Georges Favreau for older browsers and a JAVA language program called JCrystal by Steffen Weber for the java-capable browsers. The example crystals in each group and class were constructed using the following parameters: Crystallographic axes: a=1, b=1, c=1.

Crystallography From LoveToKnow 1911 CRYSTALLOGRAPHY (from the Gr. KpuaraAAos, ice , and to write), the science of the forms, properties and structure of crystals. Homogeneous solid matter, the physical and chemical properties of which are the same about every point, may be either amorphous or crystalline. In amorphous matter all the properties are the same in every direction in the mass; but in crystalline matter certain of the physical properties vary with the direction. The essential properties of crystalline matter are of two kinds, viz. the general properties, such as density , specific heat, melting-point and chemical composition, which do not vary with the direction; and the directional properties, such as cohesion and elasticity , various optical, thermal and electrical properties, as well as external form. By reason of the homogeneity of crystalline matter the directional properties are the same in all parallel directions in the mass, and there may be a certain symmetrical repetition of the directions along which the properties are the same. When the crystallization of matter takes place under conditions free from outside influences the peculiarities of internal structure are expressed in the external form of the mass, and there results a solid body bounded by plane surfaces intersecting in straight edges, the directions of which
