Isotopically pure diamond C or 100% C. The isotopes of carbon can be separated in the form of carbon dioxide gas by cascaded chemical exchange reactions with amine carbamate. Such CO can be converted to methane and from there to isotopically pure synthetic diamonds. Isotopically enriched diamonds have been synthesized by application of chemical vapor deposition followed by high pressure. The C isotopically pure, (or in practice 15-fold enrichment of isotopic number, 12 over 13 for carbon) diamond gives a 50% higher thermal conductivity than the already high value of 900-2000 W/(m·K) for a normal diamond, which contains the natural isotopic mixture of
Element Six oil and gas drilling to precision machining and electronics. Products offered by Element Six fall into two broad categories - superabrasives and advanced diamond products. The largest part of the company's business today is in superabrasives. These products are based on the world's hardest materials such as synthetic diamond and cubic boron nitride that are used in a wide range of cutting, grinding and drilling applications range from oil and gas exploration to machine tools, automotive part manufacturing and marble production.
