amorphous

(of chemicals, rocks, etc.) not having a crystalline structure

Amorphous

Those forms that do not have a definite or specific shape; or a distinctive crystalline, geometric, angular or curvilinear structure.

amorphous

[ə′mȯr·fəs]
(physics)
Pertaining to a solid which is noncrystalline, having neither definite form nor structure.

amorphous

Said of rock having no crystal structure.

amorphous

Unorganized or vague. A lack of structure. For example, the amorphous state of a bit on a rewritable optical disc means that the light from a laser beam will scatter and not be as reflective as a highly structured crystalline bit. Contrast with crystalline. See amorphous silicon, amorphous semiconductor, phase change disc and phase change memory.
