Erratum to: J Mater Sci DOI 10.1007/s10853-009-3474-z

In the original version of this article, values of standard reduction potentials in Eqs. (4), (5), (7), (8) and (9) were unfortunately miscopied. The correct values are as follows:

in Eq. (4), \( \Updelta {{E}}^\circ = 0.62\,{\text{V}} \)

in Eq. (5), \( \Updelta {{E}}^\circ = 0.17\,{\text{V}} \)

in Eq. (7), \( \Updelta {E}^\circ = -0.65\,{\text{V}} \)

in Eq. (8), \( \Updelta {{E}}^\circ = -0.62\,{\text{V}} \)

in Eq. (9), \( \Updelta {{E}}^\circ = -0.82\,{\text{V}} \)

Accordingly, the 4th sentence following Eq. (9) should be:

“This is particularly true for Ca3B2O6 where the value is ΔE° = −0.82 V.”
