Abstract
Nanosized Beta carbon nitride crystal has been synthesized by ball milling method. The graphite powders were first milled for 200 h under the presence of the NH3 gas with 300 kPa. And then they were annealed for 4h in the ammonia gas flow at 650°C. XRD result showed that the structure of the most as-synthesized products were β-C3N4 signal crystal with few α-C3N4. SAED and FTIR confirmed that the compositions of the products were carbon nitride crystal.
