    Abstract
  • We reported some main features of shock synthesized wBN ceramic powders by its morphology, specific surface area, microdensity, crystallite size as well as the B to N atomic ratio. These will reflect, from anoth side, the unique high defect density which exists in the wBN crystals. We also analyzed the observed behavior of wBN powders under ambient pressure and high temperature (up to 1 500 ℃) by TG and DTA observation in air, N2 and Ar gas.
