A solid that does not have a repeating, regular three-dimensional arrangement of atoms, molecules, or ions.

"shapeless," 1731, from Modern Latin amorphus, from Greek amorphos "without form, shapeless, deformed," from a- "without" (see a- (3)) + morphe "form" (see Morp [..]

Without a defined crystalline shape. Opal is an example of an amorphous mineral.

adj. Without determinate shape.

term used to describe a solid which does not exhibit crystalline structure. While there may be local ordering of the atoms or molecules in an amorphous solid, no long-term ordering is present.Examples [..]

Devoid of crystallinity. Most plastics are in the amorphous state at processing temperatures; many retain this state under normal conditions.

Solids which have neither definite form nor structure.

[adjective] Having no specific arrangement or organization. Amorphous solids are those that have no specific arrangement of atoms and usually melt over a broad temperature range and break unpredictably, producing fragments with irregular, often curved surfaces. Appears in modules:

(adj) having no definite form or distinct shape(adj) lacking the system or structure characteristic of living bodies(adj) without real or apparent crystalline form

An amorphous material is a solid. However its molecules are not oriented within a cristallin structure but are irregularly distributed like in a liquid. The material is solid because the molecules are frozen in their position. Very often with increasing temperature the molecules become more and more movable and, without having a precise melting poi [..]

Without definite shape or structure, without crystalline structure.

Non-crystalline.

lacking a defined shape or structure

having no definite shape or boundaries; a term applied to rocks and minerals that have no definite crystalline structure.

Without form; applied to rocks and minerals which have no definite external crystalline structure.

Without a crystalline shape.

The adjective amorphous, when applied to gemstones and gem materials, means a substance lacking crystalline structure. Amber and glass are examples of amorphous materials.

Literally “without form”; describes minerals that lack definite crystal structure. Example: Obsidian, a high-silica, non-crystalline, natural volcanic glass.

Without crystalline structure or definite shape e.g. glass, amber, precious opal.

<cell biology> Having an irregular or undefined shape or structure. (05 Feb 1998)

admitting a wide variety of shapes; often used as an adjective for a one-diamond opening that might be based on a balanced hand with only two or three diamonds, or for one that might be based on short [..]

Materials such as glass, which have no regular repeating crystalline structure. Source: Clay: A Studio Handbook

Without crystallization in the ultimate texture of a solid substance. Used to describe the material structure in the tripped state of a Multifuse® device.

quality of solid materials which do not have regular spatial arrangement of atoms in a long distance (e.g. glass)

Having no defined shape or form such as free form sculpture.

A solid not having a repetitive three-dimensional pattern of atoms.

Amorphous material contains atoms in an irregular shape rather than an ordered structure. An amorphous state is generated via rapid heating or cooling. The opposite of an amorphous structure is a crys [..]
