Carbon black
When natural gas is burnt in limited supply of air, the resulting soot is deposited on the underside of a revolving disc. This is carbon black and it is then scraped off and filled in bags. It differs from lamp black in being not so greasy. Carbon black..
Amorphous Carbon - Lamp Black
Lamp Black is also known as Soot. Soot is obtained by the incomplete combustion of carbonaceous, fuels, especially oil fuels, in limited supply of air. The soot settles on the cooler parts of the chamber, and can be collected by scrapping it (Fig.10.5). It is used in the manufacture of pr..

Tests for Carbon Monoxide - 1. Carbon monoxide is colourless, neutral gas. 2. It burns in air or oxygen with a pale blue flame to form carbon dioxide. 3. Carbon monoxide has no action on limewater, whereas carbon dioxide turns limewater milky. 4. A ..
Amorphous Forms of Carbon
Coal - Coal is formed in nature by the 'carbonisation' of wood. Conversion of wood to coal under the influence of high temperature, high pressure, and in the absence of air is termed carbonisation. Amongst coal varieties, anthracite is the purest form. It contains about 94 - 95% of carbon..

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 it is placed in water, it will sink (Fig.10.7)..

. Destructive distillation of coal gives products like coal gas, gas carbon, coal tar and ammonical liquor. Lamp black, an amorphous form of carbon is produced by the incomplete combustion of carbonaceous fuels. Wood charcoal is used as a domestic fuel due to its low i..
Hardening of Natural Rubber
Rubber can be hardened by adding carbon black as a filler (solid substance added for strength and to reduce the cost) to it during the vulcanization process. This increases the strength and abrasion resistance of natural rubber. Carbon black when mixed with ..
