Crystallography, though, is very often subdivided into different flavors. CLASS NOTES. Crystallography 2. By contrast, the crystalline state is characterised by a regular arrange-ment of atoms over large distances. CRYSTALLOGRAPHY is simply a fancy word meaning "the study of crystals The study of crystalline solids and the principles that govern their growth, external shape, and internal structure Crystallography is easily divided into 3 sections - geometrical, physical, and chemical. Crystallography. (i) The Law of constancy of the interfacial angles : This law states that angle between the adjacent corresponding faces is the inter facial angles of the crystal of the particular substance is always constant inspite of having different shapes and sizes and mode of growth of crystal. Question: Is there an finite ways to arrange atoms in a regular way in 2, and 3 dimensions? This article explains how it works, what it can be used for and a step-by-step explanation of the workflow.
