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 vapour deposition technology opened the opportunity to synthesize diamond films and a new raft of application areas became possible. In 2002, the company changed its name to Element Six and its business focus moved towards building an enterprise based on advanced material applications for increasingly sophisticated engineering customers backed by global technical support and a strong research and development organization. In 2013 Element Six opened the world’s largest and most sophisticated synthetic diamond research and development facility. The Global Innovation Centre, near Oxford, UK develops a pipeline of innovative synthetic diamond and related supermaterial products for customers, in industries from
