Anthracite is a noun that refers to a type of coal with a high carbon content and a low level of impurities. It is considered to be the highest grade of coal due to its hardness, low moisture and volatile matter, and high energy content.
Anthracite is formed through a geological process called metamorphism, where organic material, such as vegetation, is subjected to high pressure and temperature over a long period of time. This process removes the volatile components from the organic matter and increases the concentration of carbon, resulting in the formation of anthracite.
Due to its high carbon content, anthracite burns cleanly and efficiently, producing a steady and intense heat. It is primarily used as a fuel source for heating and cooking, particularly in residential heating systems and industrial applications such as power plants and steel production. Anthracite is also used in the production of electricity and as a raw material in the manufacturing of carbon electrodes, foundry coke, and other carbon-based products.
The term "anthracites" is the plural form of anthracite, used to refer to multiple occurrences or types of anthracite. It can also be used to describe a group or collection of anthracite samples or deposits found in different locations.
The word anthracites is derived from the Greek word anthrakites, which means coal-like. It is a combination of the Greek word anthrax, meaning coal, and the suffix -ites, which denotes pertaining to or resembling.
