Crystallographic axes
WebJan 26, 2016 · The Y axis is aligned parallel to the crystallographic b axis. The X axis is set in the a* direction (perpendicular to the b and c axes). The Z axis is chosen to satisfy a right-handed coordinate system. This convention is different from that used by Ryzhova who also set the Y axis parallel to the b axis but then set the Z axis parallel to c*.

WebBiaxial crystals have three different crystallographic axes. They also have two unique directions within the crystal that resemble the unique optic axis in a uniaxial crystal. The Greek letters α (alpha), β (beta), and γ (gamma) … WebThe tetragonal unit cell is distinguished by an axis of fourfold symmetry, about which a rotation of the cell through an angle of 90° brings the atoms into coincidence with their initial positions. The elements boron and tin …
WebIt intercepts the crystallographic axes at the points [100], [010], and [001]. The plane (210) intercepts the crystallographic axes at [1/2 0 0], [010] and does not intercept the c-axis. Lattice planes are very important in that they can act as diffraction gratings to radiation that has a wavelength comparable in size to the spacing between 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.
http://www.clay.uga.edu/courses/8550/millerindices.html 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.
WebThis alternate form of describing the hexagaonal system with four crystallographic axes is known as the Bravais-Miller system. The symbolic notation for this system is given as ( hkil ), where the first three integers refer to the three identical axes, respectively. In this notation, h + k = - i Closures for crystallographic indices
