Figure 6
Variation of hexagonal cell parameters with time for the K-series rhombohedral phase syntheses at 368 K. Black squares = K3; grey triangles = K2; white circles = K1. The literature values of (K0.368H3O0.05)Fe3(SO4)2(OH)6–H3OFe3(SO4)2(OH)6 (Basciano & Peterson, 2007) are shown as black filled squares joined by a solid line. |
