PROPERTIES AND CHARACTERISTICS OF GRAPHITE

Carbon alone forms the familiar substances graphite and diamond. Both are made only of carbon atoms. Graphite is very soft and slippery, while diamond is one of the hardest substances known to man. Carbon, as microscopic diamonds, is found in some meteorites. Natural diamonds are found in ancient volcanic pipes such as found in South Africa.

What Is the Chemical Formula for Graphite?

Graphite's chemical formula is C. Graphite is a carbon allotrope, meaning that it has the same chemical composition as carbon, but it has different physical characteristics. Carbon is capable of forming three naturally occurring allotropes: amorphous carbon, graphite and diamond. When carbon atoms form a hexagonal crystal structure, the result is graphite.

Graphite (C) - Classifications, Properties & Applications

Graphite flake can be found as a lamella or scaly form in specific metamorphic rocks such as limestone, gneisses, and schists. Froth flotation is used to extract flake graphite. Floated graphite has 80%90% graphite content. Over 98% of flake graphite is made using chemical beneficiation processes.

Diamond and Graphite - GemSelect

Both diamond and graphite have a very simple chemical composition; they are both pure carbon. Yet diamond is the hardest mineral known to man (10 on the Mohs scale), and graphite is one of the softest (less than 1 on the Mohs scale). As a result, diamond is the ultimate abrasive, whereas graphite is an excellent lubricant.

The purity of hot isostatic pressing graphite reaches 99.99%. This graphite was dense with an average particle size of 25 μm and a pore size of 0.7 μm. Before the corrosion tests, the graphite crucibles were cleaned with ethanol, and then heated in argon atmosphere at 700 °C for 24 h to remove the absorbed water and oxygen in graphite.

Pure graphite is one of the most chemically inert materials. It is resistant to most acids, alkalies and corrosive gases. However impurities are almost always present to some degree in both natural and artificial graphites and often have an important catalytic effect with resulting increase in the chemical reactivity. The anisotropy of the graphite crystal is reflected in its chemical behavior ...
