This article is a 'stub' page, it has no, or next to no, content. It is here at the moment to help form part of the structure of SklogWiki. If you add sufficient material to this article then please remove the {{Stub-general}} template from this page.

Plastic crystals are a state of matter whose almost-spherical molecules are located on crystalline lattice points, but have a degree of rotational disorder. Plastic crystals exist over a narrow temperature range; the temperature being sufficiently high so as to overcome any rotational energy barriers, but sufficiently low so as not to disrupt the lattice structure.
