  • PROPERTIES AND CHARACTERISTICS OF GRAPHITE

    2017-9-20 · Thermodynamically, graphite at atmospheric pressure is the more stable form of carbon. Diamond is trans-formed to graphite above 1500°C (Figure 1-4). The structure of graphite consists of a succession of layers parallel to the basal plane of hexagonally linked carbon atoms. The ideal graphite structure is shown in Figure 1-5.

    2018-5-3 · In fact, technically speaking, graphite has no melting point until you get to approximately 100 atmospheres [8]. And at the point, the melting point is between 3,600-4,200°K, which is approximately 6,000-7,000°F [9]. This is roughly two thirds the temperature of our sun’s photosphere [10].
