Figure 1
Representation of the ettringite crystal structure shown down the y(b) axis [panel (a)] and the z(c) axs [panel (b)] (Goetz-Neunhoeffer & Neubauer, 2006). Panel (c) shows a `cross-sectional' view of the hydrotalcite LDH structure shown down the y(b) axis (Radha et al., 2007), where Mg = Mg or Al. Not to scale. |
