In 1801 René Haüy, a French mineralogist, described one of the first coherent theories of crystal structure, published as the Treatise of Mineralogy. From this start grew the science of crystallography, the study of crystals and their...

Crystallography is the study of materials in which the atoms stack in a three-dimensionally ordered geometric arrangement. In a single crystal a single pattern extends throughout the entire material. Polycrystalline materials have discontinuities in...

A crystal is a patterned three-dimensional assembly of atoms that is a repetitive (periodic) array of atoms. Crystals contain repeating arrays or atoms arranged in unit cells. Crystallography is the study of the formation processes that produce...

In the early years of science, crystals were considered a strange union of the animal and mineral kingdoms, growing into predetermined shapes like living things but seemingly without life. Many mineralogists hypothesized that their growth was the...

X-ray crystallography is a process by which the extremely fine atomic structure of many crystals can be examined and recorded. It was first developed not as a research tool but as a means of determining the nature of x rays themselves. X rays were...

Branch of science that deals with discerning the arrangement and bonding of atoms in crystalline solids and with the geometric structure of crystal lattices. Classically, the optical properties of crystals were of value in mineralogy and chemistry for...

For the book of poetry, see Crystallography (book). Crystallography (from the Greek words crystallon = cold drop / frozen drop, with its meaning extending to all solids with some degree of transparency, and graphein = write) is the experimental science...
