WebAnswer: “Amorphous” refers to a solid that lack a regularly repeated atomic pattern. When an atomic pattern is regularly repeated in 3 dimensions, the resulting solid is said to be …
WebAmorphous material is one kind of nonequilibrium material; its characteristic of atomic arrangement is more like liquid and has no long-range periodicity. The glass-forming ability of an alloy is closely related to its composition, and is quite different in various alloys. WebKinds of Solids —crystalline solids vs. amorphous solids-crystalline solids have long range order; amorphous solids do not have long range order Crystalline Solids are ionic, molecular, covalent network, or metallic examples: ionic —e.g., NaCl; built from attraction of cations with anions molecular —e.g., sucrose; discrete molecules held together by intermolecular …
WebNov 14, 2014 · As a consequence graphite with its extensive 3 dimensional planar array of ordered carbon atoms is crystalline. Whereas the fibers, being ordered over a much smaller range, are amorphous. The amorphous nature of the fiber allows the smaller ribbons to bend and fold, and mechanically interlock with one another. WebAmorphous carbon is the name used for carbon that does not have any crystalline structure. As with all glassy materials, some short-range order can be observed, but there is no long-range pattern of atomic positions.
