Crystallography and crystal chemistry
WebCrystallography is the experimental science of determining the arrangement of atoms in crystalline solids.Crystallography is a fundamental subject in the fields of materials science and solid-state physics (condensed matter physics).The word crystallography is derived from the Ancient Greek word κρύσταλλος (krústallos; "clear ice, rock-crystal"), with its … WebCrystallography is the science that examines crystals, which can be found everywhere in nature—from salt to snowflakes to gemstones. They are part of a cadre of …
