thumbGraphite () is a crystalline allotrope (form) of the element carbon. It consists of many stacked layers of graphene, typically in excess of hundreds of layers. Graphite occurs naturally and is the most stable form of carbon under standard conditions. Synthetic and natural graphite are consumed on a large scale (1.3million metric tons per year in 2022) for uses in many critical industries including refractories (50%), lithium-ion batteries (18%), foundries (10%), and lubricants (5%), among others (17%). Graphite converts to diamond under extremely high pressure and temperature. Graphite's
Graphite is a naturally occurring crystalline form of carbon made up of many stacked layers of graphene, and it is the most stable form of carbon under normal conditions. It is widely used across many industries—particularly in refractories, lithium-ion batteries, foundries, and lubricants—with over 1.3 million metric tons consumed annually worldwide.

الغرافيت هو معدن متوافر بشكل طبيعي بكثرة وهو أحد أشكال الكربون المتآصلة وذلك بالإضافة إلى الألماس والفوليرين. الغرافيت موصل للكهرباء ويمكن استخدامه على سبيل المثال في أقطاب الأقواس الكهربائية. يتبلور الغرافيت غالباً بنظام سداسي ونادراً ما يكون بالنظام الثلاثي، ويشكل بلورات بنية إلى سوداء أو رمادية لها شكل سداسي الأضلاع أو متوازي الأضلاع (لوح)، أو تكون على شكل قشور. وجود الغرافيت في حديد الزهر هو سبب ضعف هذا النوع من الحديد عندما يتعرض لشد. ولا يُعرف طريقة للتخلص منه.
