How Do You Make Diamonds From Coal?
A diamond is a form of carbon in which the carbon atoms are arranged in a crystal structure such that each carbon atom is surrounded by four other carbon atoms to form a perfect tetrahedron. This structure is extremely stable, and diamonds are the hardest naturally occurring substance. Coal is an amorphous form of carbon that can be transformed into diamond with a high pressure, high temperature (HPHT) process. This occurs in nature over millions of years and there are several different processes that can accomplish this artificially. Use HPHT processes to produce very small diamond chips within a few hours. These diamonds are not suitable as gemstones and are primarily used to coat the edges of cutting tools. Make diamonds with a belt press. Upper and lower anvils press on an inner cell containing carbon. The pressure is usually confined internally with steel bands, although this may also be accomplished with hydraulic pressure. Belt presses were the first technique for creating diamo
