Formally, this prototype reaction serves for cations as well as anions. Cations by definition always have positive Z values and derive from metal atoms. As an example of this, the following reaction, which would apply to the zirconium constituent in the well known solid electrolyte calcia-stabilized zirconia (CSZ), may be cited... 

Nemst [1,2] studied the behavior of solid ionic conductors— high temperamre ceramics—for use as filaments in light bulbs. Nernst made a breakthrough discovery based on the observation of different types of conductivity in stabilized zirconia, or zirconium oxide doped by a few mole per cent of calcia, magnesia, yttria, etc. At that time, the use of other materials for this purpose was problematic due to their unfavorable resistance characteristics—a rise in temperature caused an increase in resistance, and thus the metal wires were not able to obtain a...
