Zishment, Netherlund). The lattice thermal expansion perpendicular and parallel to the basal planes of different pyrocarbon structures formed in a ff uidized bed has been measured by X-ray diffraction over the temperature range ZOO-1200°C. The results are correlated to the structuraf parameters char
