Crystal Types - Shapes & Structures
Let's take a look at the two main ways to categorize crystal types. I've described the major crystal structures (e.g., triclinic, hexagonal) and how crystals are classified by their properties (e.g., ionic, covalent) and provided links so that you can see examples of crystal types and learn more about crystallography.
