amorphous carbon

Let us learn about amorphous carbon

Amorphous carbon reactive carbon is an allotrope of carbon which does not have any crystalline structure. As with all glassy materials, certain short-range order can be observed. Amorphous carbon is frequently abbreviated to aC for general amorphous carbon, aC:H for hydrogenated amorphous carbon, or to ta-C for tetrahedral amorphous carbon

Amorphous forms of carbons includes of coal, charcoal & carbon black. Millions of years ago, due to geographical changes, plants were buried under the earth crust. High temperature & absence of air converted them to coal is a complex material consisting mainly of hydrocarbons & other organic compounds. Amorphous carbon contains 60 to 90% carbon together, oxygen. Nitrogen, sulphur, aluminium & silicon when coal is heated at high temperature, it decomposes producing a variety of gases and liquid products. The mixture of gases that are largely methane, hydrogen & carbon monoxide is known as coal gas & the mixture of liquids containing hydrocarbons other organic compounds is known as coal tar. The solid residue left during this process is known as coke. It contains 90 to 95% carbon.


In our next blog we shall learn about fibrous joint I hope the above explanation was useful.Keep reading and leave your comments.
