PbO2 electrodes exhibit symmetry on the CV curve in MnSO4 bath (oxidation peak occurs at 1.00–1.40 V) and asymmetry in Mn(NO3)2 plating solution (negative current value at 1.00–1.18 V). The current rapidly rises to a large peak current at 1.25 V.

Addition of small amounts of erbium has a profound effect on recrystallization and grain growth in titanium. Erbium, because of its negligible solubility in titanium, precipitates in the titanium matrix as a finely dispersed second phase. The presence of this phase, depending on its average size, distribution, and volume fraction in titanium, strongly inhibits the migration of grain boundaries during recrystallization and grain growth, and thus produces ultimate grains of sub-micrometer dimensions. A systematic investigation has been conducted to study the isothermal grain growth in electrolytically pure titanium and titanium-erbium alloys (Er concentration ranging from 0-0.3 at.%) over the temperature range of 450 to 850°C by electron microscopy.
