Asbestos (Crocidolite)

Lattice spacings 0.903 and 0.452nm

These crystals occur as long needles and display good diffraction patterns.  The planes parallel with the long axis of the crystals are of the 0.903nm spacing; the planes of spacing 0.452nm lie at about 60 degrees to this.

Some of the crystals in the preparation show a globular structure under electron irradiation, but a good proportion of the crystals appear unaffected by the beam, and yield clear lattice pictures.
