Before a cremation diamond can grow, we have to increase the purity of the isolated carbon. In order to increase purification, impurities must be removed and vaporised. The distinct graphite structure is then created.
This is achieved by heating up the amorphic carbon from 2,500°C up to 2,700°C in a vacuum environment.
Past this stage of process, the graphite reaches a purity of approximately 99%. The arrangement of the carbon atoms in the graphite structure is essetial to significantly advancing the subsequent diamond synthesis.
