According to the structure 12  Classification of Materials ctd. According to the structure Crystalline material is a material comprised of one or many crystals. In each crystal, atoms or ions show a long-rage periodic arrangement. A single crystal is a crystalline material that is made of only one crystal (there are no grain boundaries) Grains are the crystals in a polycrystalline material. Grain boundaries are regions between grains of a polycrystalline material. Polycrystalline material is a material comprised of many crystals (as opposed to a single-crystal material that has only one crystal) Amorphous materials are non-crystalline, that is they lack long-range regularity in their atomic structure. 13 Q&A? 14
