WebNov 4, 2024 · Crystallinity can range from 0 percent (entirely amorphous) to 100 percent (entirely crystalline), but most polymers fall somewhere between those extremes. It’s important to know this because the physical properties of a polymer, such as density, ductility, and yield strength, are all highly dependent on how amorphous or crystalline it is.

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. Amorphous materials, such as liquids and glasses, represent an intermediate case, having order over short distances (a few atomic or molecular spacings) but n… WebIllite crystallinity is a technique used to classify low-grade metamorphic activity in pelitic rocks. [1] Determining the " illite crystallinity index " allows geologists to designate what metamorphic facies and metamorphic zone the rock was formed in and to infer what temperature the rock was formed. Several crystallinity indices have been ...
