Internal displacement parameter tables

This expression has been evaluated by using the internal displacement parameter of Table 8-4 and, in Table 9-4, the resulting e, are compared with values derived from experimental piezoelectric constants compiled by Martin (1972a). The...

Particle density is an important parameter in defining the aerodynamic behaviour of airborne particles. Small quantities of selected batches (ca. Ig of FS3, FS4, FS5 and FS6) were placed in the sample chamber of a helium pycnometer (model 1305 Multivolume Helium Pycnometer, Micromeritics Ltd, Basingstoke, UK), and the particle density determined from the volume of helium displaced, assuming there were no inaccessible voids within the particles. The four measurements (each of which was the mean of 4 to 6 separate determinations (Table 3)) were within the density range of 2.91 to 3.26 X 1Q3 kg m-3 quoted for natrojarosite. These studies confirm the validity of the x-ray diffraction measurements, and also indicated that the particles were substantially free of internal voids.
