 (kwā′zī-krĭs′təl, kwä′zē-)
A structural form of matter that is less orderly than a crystal and more orderly than a glass.

qua′si·crys′tal·line adj.


(ˌkweɪ zaɪˈcrys tl, ˌkweɪ saɪ-, ˌkwɑ si-, -zi-)
a form of solid matter whose atoms are arranged like those of a crystal but assume patterns that do not exactly repeat themselves.
