| Abstract: | C3N4 crystals with the size of several micrometers have been synthesized from C3N4H4 in the presence of nickel-based alloy or cobalt as catalyst under high pressure of 7 GPa and temperature of about 1400°C
for 10 min. Scanning electron microscopy, energy-disperse X-ray analysis, and X-ray diffraction were used to examine the grown
crystals. The general rule on selecting the starting materials for synthesis of carbon nitride crystals at high pressures
and high temperatures is suggested. |
