New page

A '''paracrystal''' is a kind of partially disordered crystal; wherein some forms of short and medium-range order of the [[lattice]] is present, but where long-range ordering (in at least one direction) does not exist. Many real materials are best though of as paracrystals (and not perfect crystals). I.e. in real materials there is often a well-defined local packing, essentially a [[unit cell]], but this packing does not persist indefinitely without some kind of distortion.

In [[scattering]], paracrystal disorder leads to specific kinds of [[peak width|peak broadening]] and [[peak shape]]s.
