Scanning electron micrographs of quicklime demonstrate the dramatic change in structure resulting from the sintering process, for the same high-calcium quicklime (Fig. 15.7). The effects of sintering on lime reactivity are described in section 13.2.

Synthetic hydrotalcites employed in plastics applications are finely divided, free-flotving, odorless, amorphous powders. For polyolefin applications, hydrotalcites with an average particle size of 0.5 (tm and a specific surface area ofless than 20 m /g (BETmethod) are recommended. Their density varies around 2.1 g/cm depending on the composition. Sodium, zinc, and calcium stearate-coated hydrotalcites are available, which show enhanced compatibility with polyolefins [13]. Figure 20.3 is a scanning electron micrograph of a typical submicron-size synthetic hydrotalcite [20].
