Graphite (/ ˈɡræfaɪt /) is a crystalline allotrope (form) of the element carbon. It consists of many stacked layers of graphene, typically in the excess of hundreds of layers. Graphite occurs naturally and is the most stable form of carbon under standard conditions.

Graphite is a mineral of extremes. It is extremely soft, cleaves with very light pressure, and has a very low specific gravity. In contrast, it is extremely resistant to heat and nearly inert in contact with almost any other material. These extreme properties give it a wide range of uses in metallurgy and manufacturing.

Graphite is a soft, crystalline form of carbon. Other forms are diamond and fullerenes ("buckyballs"). It is gray to black, opaque, and has a metallic luster. It is flexible but not elastic. …

2025年1月30日 · graphite, mineral consisting of carbon. Graphite has a greasy feel and leaves a black mark, thus the name from the Greek verb graphein, “to write.” Graphite has a layered structure that consists of rings of six carbon atoms arranged in widely spaced horizontal sheets.

2023年6月1日 · Graphite has a wide range of characteristics and applications. It is the most stable form of carbon under normal conditions and occurs naturally. What is the composition of graphite? Why can graphite conduct electricity while diamond cannot? Where can you find graphite in nature? Why graphite is soft? Is graphite a metal?

2023年4月23日 · Graphite is like diamond, It is a form of native carbon crystalline with its atoms arranged in a hexagonal structure that is opaque and dark gray to black. It occurs as hexagonal crystals, flexible sheets, scales, or large masses. It may be earthy, granular, or compact.

Graphite is a common allotrope of carbon and is distinctively the most stable form of carbon (even more so than diamond) under standard conditions. It is unique in that it has properties of both a metal and a non-metal: it is flexible but not elastic, has a high thermal and electrical conductivity, and is highly refractory and chemically inert.

Simple generation and detection of polyynes in an arc discharge between graphite electrodes submerged in various solvents. This graphite blanket has many holes of small diameter and …

2002年9月10日 · Graphite is a distinct material as it displays the properties of both a metal and a non-metal. Although graphite is flexible, it is not elastic and has high electrical and thermal conductivity. It is also chemically inert and highly refractory.

Graphite can be engineered to obtain specific properties such as density, electrical resistance, hardness, porosity, compressive strength, flexural strength, coefficient of thermal expansion and thermal conductivity. Typically graphite is produced from petroleum coke which is heated to incandescence, which drives off many volatiles.
