A particular form of carbon distinguished by hexagonal crystallinity. Characterized by its extreme softness (soapy feel), iron-black color, metallic luster, low specific gravity, odorless, infusibility, tasteless, non-toxic and chemically inert to acids and alkalis under most conditions.
Graphite is used in powder metallurgy as an alloying element to increase the strength of sintered parts. It can also be used as an additive in specialized refractories, for hot metal toppings, and to make porcelain boats for compression molds and sintering.
Graphite is also a strong heat and energy conductor, making it useful in electrical devices such as electrodes, batteries, and solar panels.
