Definitions

  • the invention relates to a mesophase pitch derived carbon fibre which has been boronated and intercalated with calcium.
  • boron and about 1% by weight calcium provides a good quality carbon fibre according to the invention.
  • the amount of calcium intercalation must be determined experimentally by varying the amount of the calcium compound used and the treatment time.
  • vapour pressure of the boron is much lower than the calcium.
  • the boronation is a result of atomic diffusion whereas the intercalation of calcium is a result of vapour diffusion.
  • Examples 94 to 109 do not include the preferred calcium to boron weight ratio but the trend of resistivity versus calcium content shows the characteristic increase in resistivity for a calcium to boron weight ratio less than 2:1.
  • the interlayer spacing increases from a calcium content of about 3.8% to 8.5% by weight and would be expected to be a maximum at about 10% by weight in accordance with the invention.
