Physical Properties

The physical parameters
  • particle size distribution
  • specific surface area
  • particle morphology
are determined by control of the nitridation variables and post-synthesis powder processing e.g milling, classification and other treatments. Standard B.E.T. specific surface areas of the micronsized SICONIDE area at the 6 m2/g and 12 m2/g levels.
