without, morphé, shape, form) or non-crystalline solid isa solid that lacks the long-range order that is characteristic of a crystal. In some older books, the term has been used synonymously with glass. ... Polymers are often amorphous. ...
Glass is a non-crystalline, often transparent amorphous solid, that has widespread practical, technological, and decorative use in, for example, window panes, tableware, and optics. Glass is most often formed by rapid cooling (quenching) of the molten form; some glasses such as volcanic glass ...

Amorphous glass contains (wt.%) 55-63.5 SiO2 4-10 Al2O3 and 0.1-3 MnO with the remainder CaO + Na2O + MgO + TiO2 to total 100%, and beyond this 0.5-8% F and 0.1-1% ZnO. Specif., the ranges are 59-63.5 SiO2, 6-8.5 Al2O3, and 0.1-1.5 MnO, with 22.2-26.9 CaO, 4.8-...
Glass is anamorphoussolid ornoncrystalline solidwhich do not possess long range periodic order in their constituent atoms, but they preserve short-range order[19]. These are distinctive classes of amorphous solids which exhibit glass transition phenomenon upon heating[20]. In glassy materials, the ...
Below the melting point, this solid crystalline structure is the most stable form, and above the melting point, the liquid form becomes more stable. All materials want to adopt their most stable form, which is known as being in equilibrium. However, glass is unusual because it doesn't exist...
Ceramics exist as both crystalline and non-crystalline (amorphous) compounds. Glasses and partially crystallised glasses, known as glass-ceramics, are therefore subclasses of ceramics. A common characteristic of all ceramic materials is that they are subjected to high temperatures during manufacture or ...
