Graphite is a polymorph of the aspect carbon. design is accession polymorph. The two allotment the aforementioned chemistry, carbon, but accept absolute altered structures and absolute altered properties.
Diamond is the hardest mineral accepted to man, Graphite is one of the softest.
Diamond is an accomplished electrical insulator, Graphite is a acceptable aqueduct of electricity.
Diamond is the ultimate abrasive, Graphite is a absolute acceptable lubricant.
Diamond is usually transparent, Graphite is opaque.
Diamond crystallizes in the Isometric arrangement and graphite crystallizes in the hexagonal system.
Somewhat of a abruptness is that at apparent temperatures and pressures, Graphite is the abiding anatomy of carbon. In fact, all precious stones at or abreast the apparent of the Earth are currently ability a transformation into Graphite. This reaction, fortunately, is acutely slow.
All of the differences amid graphite and design are the aftereffect of the aberration in their corresponding structures. Graphite has a area like anatomy area the atoms all lie in a even and are alone abominably affirmed to the graphite bedding aloft and below. Design has a framework anatomy area the carbon atoms are affirmed to added carbon atoms in three ambit as adjoin to two in graphite. The carbon-carbon bonds in both minerals are in fact absolutely strong, but it is the appliance of those bonds that accomplish the difference.
