WebApr 10, 2024 · Crystalline definition: A crystalline substance is in the form of crystals or contains crystals. Meaning, pronunciation, translations and examples Crystallinity refers to the degree of structural order in a solid. In a crystal, the atoms or molecules are arranged in a regular, periodic manner. The degree of crystallinity has a big influence on hardness, density, transparency and diffusion. In an ideal gas, the relative positions of the atoms or molecules are completely random.
