SEM images and model of lithium metasilicate clusters. The SEM scale bar is 200 nm and 100 nm for panels a and b, respectively. Panel c shows different viewing angles of a 80 formula units of lithium metasilicate cluster. Coloring scheme is Si (yellow), O (red), and Li (pink). Longest axial measurements are 27 Å × 24 Å × 28 Å
