amorphous solids definition

Amorphous Solids - 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..

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, ru..

Solids with particles not arranged in a regular fashion. They have only short range order or even the particles are disordered in some case..

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 Crystall..

: Crystalline Amorphous In a crystalline substance, a definite well-defined external geometric shape such as cube, octahedron or tetrahedron characterizes the solid..

Classification of Solids - The above properties suggest that the properties of the solids not only depend upon the nature of the constituents, but also on their arrangements. Based on their structural features solids can be classified into three categories: Crystalline..

Nature of Solid Catalyst - Heterogeneous catalysis is extensively used in chemical industry. Hence, development, selection and application of solid catalysts forms an important area in surface chemistry studies. The nature of the solid catalyst has profound effects on ..

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. ..
