Crystal direction family
WebThe crystal directions of a family are not necessarily parallel to one another. Similarly, not all members of a family of planes are parallel to one another. 12. By changing the signs of all the indices of a crystal direction, we obtain the antiparallel or opposite direction. By changing the signs of all the indices of a plane, we obtain a ...

East, west, north, and south are the 4 cardinal directions and there are four corners called the sub directions where the two cardinal … Crystals can be classified in three ways: lattice systems, crystal systems and crystal families. The various classifications are often confused: in particular the trigonal crystal system is often confused with the rhombohedral lattice system, and the term "crystal system" is sometimes used to mean "lattice system" or "crystal family".

In Fig. 2.52, the vector r⃗, passing through the origin O to a lattice point, can be expressed in terms of the fundamental translation vectors a, b and c, which form the crystal axes. r = n 1 a + n 2 b + n 3 c ADVERTISEMENTS: where, n 1, n 2 and n 3 are integers. first pregnancy 20 weeks bellyWeb2.Count q a in the x-direction, r v in the y-direction, and sc in the z-direction. 3.Draw and label the point. In the BCC system shown in Figure1b, the path to point 9 would be 0 a in the x-direction, 1 a in the y-direction, and 1 a in the z-direction. Thus the point coordinates of point 9 are 011.
