    Abstract
  • The boron-doped diamond single crystals with different boron amounts were synthesized by adding B4C in iron-based catalyst. Based on the testing data of different thermal analysis (DTA) and thermal gravity (TG) analysis during heating process, the apparent activation energies were calculated by the Kissinger method. The effect of different boron amounts on their thermal stability and oxidation resistance were analyzed in oxidation reaction. The experimental and theoretical results showed that the variation trends of the DTA and TG are consistent with that of the apparent activation energy. In the severe oxidation process, both the thermal stability and the oxidation resistance of the boron-doped diamond single crystals increase firstly and then decrease with the increasing of boron amounts.
