抄録

Materials with high elements (C, B, N. . . ) appear to be a great interest for the future. The most dense forms of these materials are characterized by exceptional physico-chemical properties (diamond, c-BN, β-C<SUB>3</SUB>N<SUB>4</SUB>. . . ). The last material (C<SUB>3</SUB>N<SUB>4</SUB>) issued from "ab-initio" calculations has instigated the development of researches for its preparation mainly as microscopic sample (carbon-nitride thin film deposition). Recently, we have proposed a new approach for the synthesis of the graphitic phase of C<SUB>3</SUB>N<SUB>4</SUB> (g-C<SUB>3</SUB>N<SUB>4</SUB>) based on the solvothermal condensation or organic precursors (as melamine or C<SUB>3</SUB>N<SUB>3</SUB>Cl<SUB>3</SUB>). Using a non-nucleophilic basis as solvent in the pressure-temperature conditions close to 130 MPa and 250°C, the graphitic form of C<SUB>3</SUB>N<SUB>4</SUB> was prepared. The physico-chemical characterizations (XRD, Electron Probe Micro-analysis, SEM, Raman and XPS Spectroscopies) confirm this structure. Such a C<SUB>3</SUB>N<SUB>4</SUB> form appears to be a good precursor for preparing the denser forms.
