Crystal faces
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. WebCatalytic crystals contain crystal faces, edges and defects with varying activity, and progress in industrial heterogeneous catalysis critically depends on better, quantitative …

Care must be taken to see that the plane of the goniometer is at right angles to the edge of intersection between the two faces. Another model of the contact- goniometer, Fig. 378, has two arms swiveled together and separate from the graduated arc.
Webform, in crystallography, all crystal faces having similar symmetry. Those forms that enclose space are called closed forms; those that do not, open forms. The faces that comprise a form will be similar in appearance, even though of different shapes and sizes; this similarity may be evident from natural striations, etchings, or growths, or it may be … http://www.australiangold.ag/catalog/ultra/crystal-faces

Crystals form a variety of shapes depending on how the molecules pack together. These diagrams illustrate the variety of shapes. (slide 5) Crystal Surface and Growth Process. Each side of a crystal is called a face.
WebCrystal faces develop along planes defined by the points in the lattice. In other words, all crystal faces must intersect atoms or molecules that make up the points. A face is more commonly developed in a crystal if it intersects a larger number of lattice points. This is known as the Bravais Law.
