| Outline of Final Research Achievements |
The lowest temperature of synthesis of sp3 orthorhombic carbon nitride C2N2CH2 with the bulk modulus of 258 GPa of 58 % of diamond was estimated to be 2000 K at 40 GPa using sp2 nanoamorphous carbon nitride C3N4Hx synthesized with atmospheric nitrogen plasma as a precursor. Nanoamorphous carbon nitride is chemically reactive. The chemical reaction among nanoamorphous carbon nitride and rhenium metal with the bulk modulus of 352 GPa of 80 % of diamond at high pressure and high temperature resulted in the first synthesis of Re3C with the bulk modulus of 388 GPa of 86 % of diamond. The synthesis of Re3N was already known. The synthesis of Re3C was speculated that nitrogen of Re3N was replaced with C in releasing pressure. The increase of bulk modulus of 38 GPa is attributed to the introduction of an extra C-Re bond in Re3C.
