Question

Write about the amorphous form of carbon in about 100 words

Answer 1

Amorphous carbon is free, reactive carbon that does not have any crystallinestructure (also called diamond-like carbon). Amorphous carbon materials may be stabilized by terminating dangling-π bonds with hydrogen. As with otheramorphous solids, some short-range order can be observed. Amorphous carbon is often abbreviated to aC for general amorphous carbon, aC:H or HACfor hydrogenated amorphous carbon, or to ta-C for tetrahedral amorphous carbon.<br /><br />In mineralogy, amorphous carbon is the name used for coal, soot, carbide-derived carbon, and other impure forms of carbon that are neither graphite nor diamond. In a crystallographic sense, however, the materials are not truly amorphous but rather polycrystalline materials of graphite or diamond within an amorphous carbon matrix. Commercial carbon also usually contains significant quantities of other elements, which may also form crystalline impurities.
