amorphous examples

Substances whose constituents are not arranged in an orderly manner are called amorphous solids. They are also called pseudo solids and differ from crystalline solids in many respects. The common examples of amorphous solids are glass, rubber, fused silica, plastics, ..

Substances whose particles do not posses a regular orderly arrangement but have short range order. When amorphous solids are heated they become crystalline at some temperature. Properties of amorphous solids are: They do not have sharp melting point. Under go liquefaction over a..

Coal, Coke, Charcoal (or wood charcoal), Animal Charcoal (or bone black), Lamp black, Carbon black, Gas carbon and Petroleum coke. Diamonds and graphite are two crystalline allotropes of carbon. Diamond and graphite both are covalent crystals. But, they differ considerably in their properties. ..

Solids have definite shape and volume because the average distance between the molecules or atoms remain constant and do not change with time. The arrangement of molecules inside a solid differ from one to another. This results in two types of solids Crystalline solids Amorphous solids In..

Some amorphous forms of carbon are described belo..

Apart from diamond and graphite, which are crystalline forms of carbon, all other forms of carbon are amorphous allotropes of carbon. Coke Coke is the amorphous allotrope of carbon, which is derived from coal. Coal is not a true allotrope as elements like sulphur ar..

Amorphous Carbon - Wood Charcoal - Wood charcoal is obtained by the destructive distillation of wood. The chief products formed are wood charcoal, wood tar, pyroligneous acid and wood gas (Fig.10.6). However, if wood charcoal is heated strongly, most of the air gets expelled and then if i..
