AI overview

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.

Grafit (nybildning av grekiska grạphein - skriva)är ett mineral som bara består av grundämnet kol. Grafit är en allotrop av kol där atomerna bildar plana skikt med kristaller av hexagonstruktur. I grafit binder en kolatom tre andra. Inom lagren sitter atomerna fast hårt, men mellan lagren mindre hårt. Det behövs alltså ingen större yttre påverkan för att lagren ska lossna från varandra.[källa behövs] Detta gör att när man drar ett stycke grafit mot något, så lämnar det ett gråsvart streck efter sig (något som brukar kallas streckfärg).
