Graphite burning temperature

WebGraphite requires a temperature of around 6,000-7000 degrees to melt and so does diamond. These temperatures are not found anywhere on earth naturally and would require extraordinary efforts to generate. And as graphite and diamond began to melt, the carbon, assuming that there was an oxygen source, would catch fire and burn rather than melt. Web2 days ago · “And it really requires a very high temperature to make it…basically think of baking something for several weeks at a time. So it requires lots of heat and energy.” He said his company can make graphite out of coal using lower temperatures, which means a lower energy output.
