crystal face
Quick Summary
In crystallography, a crystal face refers to a flat surface that forms the exterior of a crystal. These faces are arranged in specific patterns reflecting the crystal's internal atomic structure. Crystallography is the science that studies these structures and the geometric arrangement of atoms within crystals.1234
Crystal faces can be grouped into "forms," where all faces within a form share similar symmetry. These forms can be closed, enclosing space, or open. Examples of crystal forms include pedions (a single face), pinacoids (two parallel faces), domes, sphenoids, prisms, and pyramids, among others. The external shape, or habit, of crystals is a visual manifestation of their internal architecture.156
