Crystallographic axes
WebThe crystallography of kaolinite played an important role in Linus Pauling’s formulation of the nature of the chemical bond, although for 15 years kaolinite was thought to be monoclinic (crystallographic axes all equal to 90°) instead of triclinic. Crystallographic axes: alpha, 91.8°; beta 104.7°; gamma, 90°). http://science.marshall.edu/elshazly/Mineralogy%20notes/Crystallography.doc

Web2/m – The vertical axis (The vertical axis (c) is always a fourfold axis of rotation) is always a fourfold axis of rotation. There are 4 two-fold axis of rotation: 2 parallel to the crystallographic axescrystallographic axes aand b, the others at 45the others at 45°. There are 5 mirror planes. WebMar 8, 2016 · The crystallographic axes are used mainly by crystallographers. These axes are similar to the geometric axes and are used for plotting the orientations of faces and symmetry elements in crystals. It is important to know that it is not vital that the crystallographic axes should be part of symmetry of the crystals.
WebCrystallographic axes are imaginary lines of reference inside a crystal that intersect at a common point (the crystal centre), and to which crystal faces can be referenced. Any crystal has either 3 or 4 crystallographic axes. The angles between these axes are known as the interaxial angles.
