Kimberlite

Kimberlite Definition Kimberlite is a type of peridotite consisting of a fine-grained matrix of calcite and olivine and containing phenocrysts of olivine, garnet, and sometimes diamonds. It is also called blue ground, a dark-coloured, heavy, often altered and brecciated (fragmented), intrusive ig.....

Diamond

Diamond Definition Diamond is a form of pure carbon that occurs naturally as a clear, cubic crystal and is the hardest of all known minerals. It is less stable than graphite, but the conversion rate from diamond to graphite is negligible at standard conditions. It often occurs as octahedrons with.....

Graphite

Graphite Definition Graphite is a naturally occurring, steel-gray to black, crystalline form of carbon. It is the most stable form of carbon under standard conditions. It is an enterprise-ready monitoring tool that runs equally well on cheap hardware or Cloud infrastructure. Graphite is rather co.....

About Hydrocarbon

About Hydrocarbon Definition Hydrocarbon is a class of organic chemical compounds composed only of the elements carbon (C) and hydrogen (H). Hydrocarbons from which one hydrogen atom has been removed are functional groups, called hydrocarbyls. Aromatic hydrocarbons (arenes), alkanes, alkenes, cyc.....

Fuel Cell

Fuel Cell Definition Fuel cell is like a battery in that it generates electricity from an electrochemical reaction. Both batteries and fuel cells convert chemical potential energy into electrical energy and also, as a by-product of this process, into heat energy. A fuel cell produces electricity .....
