14.4A: Graphite and Diamond - Structure and Properties ...

Graphite has a high melting point, similar to that of diamond. In order to melt graphite, it isn't enough to loosen one sheet from another. You have to break the covalent bonding throughout the whole structure. It has a soft, slippery feel, and is used in pencils and as a dry lubricant for things like locks. You can think of graphite rather like a pack of cards - each card is strong, but the cards will slide over each other, or .

Characteristics of Graphite |

ELECTRIC CONDUCTIVITY Graphite's resistivity is 2~4×10-2 Ωcm, which is a bit inferior to that of such metals as copper, silver and gold, but because graphite is less likely to be oxidized than copper and is cheaper than silver or gold, it is more widely used.

Pure Copper P/M Parts. A copper powder with a purity exceeding 99.95% is available, and, of course, the individual particles have the same properties as massive copper. However, it is impractical to achieve a density of 8.94 g/cm 1 by pressing and sintering alone, and, therefore, the properties of P/M parts are influenced by the density attained.

Lubricants and Refractories. Graphite works in this way as a lubricant up to a temperature of 787 degrees Celsius (1,450 degrees Fahrenheit) and as an anti-seize material at up to 1,315 degrees Celsius (2,399 degrees Fahrenheit). Graphite is a common refractory material because it withstands high temperatures without changing chemically.
