Crystal face index
Webcalculate the Miller Index of each face or form on the crystal using the same equations in a slightly different form as shown below: k / h = (cot Φ) / a k / l = (tan ρ) (cos Φ) / c Keep in mind that once an axial ratio is determined for a crystal, the same value for a and c should be used to calculate the Miller Index of each face. WebCrystal faces are determined by the physical properties of a crystal, such as its structure and symmetry, while cleavage planes are created by the movement of chemical bonds. Additionally, each crystal face is associated with a Miller index, while cleavage planes are always associated with the same index.
