• Crystallinity - Wikipedia

    en.wikipedia.org/wiki/Crystallinity 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 ...

    www.sciencedirect.com/topics/chemistry/crystallinity Crystallinity can be accurately measured by X-ray diffraction and less accurately but simply by specific gravity. The properties of polychlorotrifluoroethylene vary with the degree of crystallinity. Table 10.2 contains properties of two resins with different specific gravities. The crystalline resin, one with the higher specific gravity, has higher tensile yield strength and flexural modulus ...

    www.sciencedirect.com/topics/earth-and-planetary-sciences/crystallinity Crystallinity, defined as the peak width (at half maximum height) of the (104) calcite X-ray diffraction peak, is essentially a measure of how perfect the calcite crystal lattice is. As dissolution proceeds, more poorly crystallized calcite is thought to be removed, causing a narrowing of the (104) diffraction peak. ...

In a crystal, the arrangement of atoms or molecules is consistent and repetitive. Many materials such as glass ceramics and some polymers can be prepared in such a way as to produce a mixture of crystalline and amorphous regions.

Crystallinity generally is described in terms of the four categories shown in…
  • Crystallinity in Polymers

    pslc.ws/macrog/crystal.htm Crystallinity makes a material strong, but it also makes it brittle. A completely crystalline polymer would be too brittle to be used as plastic. The amorphous regions give a polymer toughness, that is, the ability to bend without breaking and the ability to absorb impact energy. These are both good properties to have.

    faculty.uscupstate.edu/llever/polymer%20resources/Crystalline.htm Semi-crystallinity is a desirable property for most plastics because they combine the strength of crystalline polymers with the flexibility of amorphous. Semi-crystalline polymers can be tough with an ability to bend without breaking, Isolated lamellar single crystals are obtained by crystallization from dilute solution. ...
  • Crystallization of polymers - Wikipedia

    en.wikipedia.org/wiki/Crystallization_of_polymers The degree of crystallinity is estimated by different analytical methods and it typically ranges between 10 and 80%, with crystallized polymers often called "semi-crystalline". The properties of semi-crystalline polymers are determined not only by the degree of crystallinity, but also by the size and orientation of the molecular chains.
