http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch13/unitcell.php The defining property of a crystal is its inherent symmetry. Performing certain symmetry operations on the crystal lattice leaves it unchanged. All crystals have translational symmetry in three directions, but some have other symmetry elements as well. For example, rotating the crystal 180° about a certain axis may result in an atomic configuration that is identical to the original configuration; the crystal has twofold rotational symmetry about this axis.

WebCrystal shapes are determined by the arrangement of the atoms within the crystal structure. For example, a cubic arrangement of atoms gives rise to a cubic-shaped mineral crystal. Crystal habit refers to typically observed shapes and characteristics; however, they can be affected by other minerals crystallizing in the same rock. WebThe Body-Centered Cubic (BCC) crystal structure is significant because it is exceedingly frequent in metals and results in interesting features such as a high ductile-to-brittle transformation temperature (DBTT). BCC is a nearly densely packed material with an APF of 0.68. Numerous features develop as a result of the fact that the next-nearest ...
