Figure 7
The lattice relationship between crystals 1 and 4 (in the figure we take the parameters a0 = c0; in fact, a0 = 10.289, c0 = 10.897 Å). (a) The common plane (10[\overline 1]0) for crystals 1 and 4. (b) The intergrowth plane between crystal 1 (0001) and crystal 4 ([\overline 1 2 \overline 1 0]). (c) The intergrowth plane between crystal 1 ([\overline 1 2 \overline 1 0]) and crystal 4 (0001).  [article HTML]
