• Description:
  Knowledge of the cross-sectional shape of mineral fibers is important for their accurate dimensional characterization. Two techniques for the measurement of width and thickness of fibers are described and compared: one for the scanning electron microscope (sem) and one for the transmission electron microscope (tem). The frequency distributions of log thickness and width determined by these techniques are considerably more accurate when the tem is used. However, the use of either technique results in essentially the identical quantitative descriptions of the relationship between thickness and width for amosite and crocidolite. A general relationship between thickness and width for amphibole asbestos is log thickness = 0.692 Log width - 0.493; A rectangle is a reasonable approximation of its cross-sectional shape.
