Hydrothermal growth of diamond particles and films was achieved during interaction of a liquid organic precursor (C₂H₃Cl₃) and 10 M NaOH in the presence of diamond or cubic BN seeds at the temperature 300 °C and 1 GPa pressure. Synthesized diamond was thoroughly characterized by TG-DTA, SEM, EDX, TE...
