Crystal Faces • Common crystal faces parallel surface of unit cell, e.g., - isometric minerals often cubes - hexagonal minerals often hexagons • Other faces often simple diagonals through lattice • Codified into two laws: (1) Law of Hauy: - Crystal faces make simple rational intercepts on crystal axes (2) Law of Bravais: - Common crystal faces are parallel to lattice planes that have high lattice node density Miller Indices • Shorthand notation for axial intercepts - works because of Law of Hauy • Miller index = integers that are inversely proportional to intercept of face or crystallographic plane with edges of unit cell.

Unformatted text preview: - general form (hkl)- h = a intercept- k = b intercept- l = c intercept Example of Miller index calculation Determining Miller Index for real crystal • Relates to the number of axial distances the face intercepts the axes Assigning Miller Indices by inspection • Prominent (and common) faces typically have small integers in Miller Indices- relate to unit cell • Face that cuts only one axis:- (100), (010), (001) etc. • Face that cuts two axes:- (110), (101), (011) etc. • Face that cuts all three axes:- (111) etc.- called unit face...
