Asbestos crocidolite
Plane spacing 0.9nm and 0.45nm
The 0.9nm spacing (020) will be found along the axis of the asbestos fibers. The 0.45nm spacing (021) appears at an angle of about 60° in suitable crystal orientations. To help prevent contamination of the EM or work area with asbestos fibers, these specimens are made using a substrate sandwich technique; the asbestos is layered between a carbon and Formvar film. Mounted on a standard 3mm TEM grid.
