WebCrystalline materials have highly defined and repeatable arrangements of molecular chains. These materials tend to have sharp melting points. Some of the common examples are diamonds, table salt, ice, sugar, and most metals. Crystallinity refers to the degree of structural order and regularity in molecular arrangements of a plastics material. WebDec 11, 2024 · A crystal or crystalline solid is a solid material whose constituents are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.
