Graphite chemical compound
Graphite is a crystalline form of the element carbon. It consists of stacked layers of graphene. Graphite occurs naturally and is the most stable form of carbon under standard conditions. Synthetic and natural graphite are consumed on large scale (300 kton/year, in 1989) for uses in pencils, lubricants, and electrodes. … See more Natural graphite The principal types of natural graphite, each occurring in different types of ore deposits, are • Crystalline small flakes of graphite (or flake graphite) … See more In the 4th millennium BCE, during the Neolithic Age in southeastern Europe, the Marița culture used graphite in a ceramic paint for decorating pottery.

WebJan 24, 2024 · Graphite is opaque and black, whereas diamond is transparent and colourless. Diamond is the hardest substance known to man, while graphite is soft and spongy. Diamond is a bad conductor of electricity; graphite is a very good conductor of electricity. Diamond and graphite are insoluble in water. One of the best studied graphite intercalation compounds, KC8, is prepared by melting potassium over graphite powder. The potassium is absorbed into the graphite and the material changes color from black to bronze. The resulting solid is pyrophoric. The composition is explained by assuming that the potassium to potassium distance is twice the distance between hexagons in t…
WebGraphite is produced by metamorphosing organic material originally deposited as sediment or mixed with sediment. As organic material is metamorphosed, hydrogen and oxygen are driven off as water, leaving the carbon behind to form graphite. Well-formed crystals of graphite are quite rare in nature, and most graphite occurs in its massive form.
