Sizing of non-spherical, sub-micron particles
Figure 4 shows the results obtained for the analysis of sub-micron, hematite spindles (oblate spheroids). The size of the particles (determined by scanning electron microscopy, or SEM) is 46.9 nm in width and 130.8 nm in length, giving them an approximate aspect ratio of 3:1. The particles are mono-sized and are readily dispersed.Web
