Graphite and diamond properties

WebMar 14, 2024 · Another solid form of carbon known as graphite is the chemically stable form of carbon at normal temperature and pressure, although diamond nearly never transforms to it. Diamond has the highest hardness and thermal conductivity of any natural substance, characteristics that make it ideal for cutting and polishing equipment in the industry. WebIt is known that graphite can be converted into diamond when subjected to high pressure and high temperatures. Assume that the difference in internal energy (E) between graphite and diamond is ΔE = 2500 J/mol and the entropy difference can be neglected, compute the minimum pressure required to facilitate the conversion.
