Abstract
Tin present in the PbO layer growing on lead-calcium-tin alloys under deep-discharge conditions (0.7 V versus SSE) has been characterized by Mossbauer spectroscopy and transmission electron microscopy. After po larization, tin is present in PbO in two valencies. Sn(IV) is predomin ant and in oxides probably precipitated at the grain boundaries, where as Sn(II) could be weakly incorporated in the PbO lattice. On the othe r hand, the crystallization of PbO is very fine, in contrast to that o f PbSO4.
