In condensed matter physics and materials science, an amorphous solid (or non-crystalline solid) is a solid that lacks the long-range order that is characteristic of a crystal. The terms " glass " and "glassy solid" are sometimes used synonymously with amorphous solid; however, these terms refer specifically to amorphous materials that undergo ...
Amorphous solids are the opposite of crystalline. The atoms or molecules in amorphous substances are arranged randomly without any long-range order. As a result, they do not have a sharp melting point. The phase transition from solid to liquid occurs over a range of temperatures. [citation needed] Some examples include glass, rubber and some ...
Vitrification (from Latin vitrum 'glass', via French vitrifier) is the full or partial transformation of a substance into a glass, [1] that is to say, a non-crystalline or amorphous solid. Glasses differ from liquids structurally and glasses possess a higher degree of connectivity with the same Hausdorff dimensionality of bonds as crystals: dim ...
Examples of materials with short range order include amorphous materials such as wax, glass and liquids [2] as well as the collagen fibrils of the stroma in the cornea. [ 3 ] Besides ordering of atoms, short-range ordering of vacancies are also possible.
An amorphous metal (also known as metallic glass, glassy metal, or shiny metal) is a solid metallic material, usually an alloy, with disordered atomic-scale structure. Most metals are crystalline in their solid state, which means they have a highly ordered arrangement of atoms. Amorphous metals are non-crystalline, and have a glass-like structure.
A glass is an amorphous solid completely lacking long range periodic atomic structure that exhibits a region of glass transformation.This broad definition means that any material be it organic, inorganic, metallic, etc. in nature may form a glass if it exhibits glass transformation behavior.
Volcanic glass is the amorphous (uncrystallized) product of rapidly cooling magma. Like all types of glass , it is a state of matter intermediate between the closely packed, highly ordered array of a crystal and the highly disordered array of liquid . [ 1 ]
Quasi-solid, Falsely-solid, or semisolid is the physical term for something whose state lies between a solid and a liquid.While similar to solids in some respects, such as having the ability to support their own weight and hold their shapes, a quasi-solid also shares some properties of liquids, such as conforming in shape to something applying pressure to it and the ability to flow under pressure.
