What are crystalline substances

A crystalline substance is a substance where the molecules, atoms or ions that compose it are in an extremely regular pattern in three dimensions. This regular pattern is called the crystal's lattice. Whether a substance solidifies as a crystal often depends on the way in which it forms, not its chemical components.

Crystalline substances are solid materials that consist of atoms, molecules, or ions and are arranged in a specific particular ordered microscopic structure that form a crystal lattice that expand out in all directions.

Examples of crystalline substances are amorphous solids which include glass, wax, and many plastics.
