WebGraphite is the most stable form of carbon under standard conditions. ", For a typical sample of Graphite the refractive index and extinction coefficient at 632.8 nm are 2.7 … WebGraphite can be converted into diamonds by the action of high temperature (~ 2000 0 C ) and high pressure (100000 atmosphere) in the presence of transition metals (such as platinum).The artificial diamonds, however, are small in size and generally grey in colour and hence cannot be used as gems. These are used for making cutting and grinding tools.
