✦ Synopsis

The site densities of the surface of different oxides and hydroxides have been calculated from crystallographic data. The following values for the common habits are recommended: 2.7 nm-2 (Corundum), 2.3 nm-2 (Boehmite and Gibbsite), 2.2 nm-2 (Hematite and Rutile), 2.1 nm-2 (Lepidocrokite), 1.9 nm-2 (Diaspore), and 1.7 nm-2 (Goethite). The probable deviations due to the variations in habits are about +/-0.2 nm-2, except Rutile (+/-0.4 nm-2). For the concrete faces the values of site density are adduced.
