Electrolytic capacitor to a smooth surface of the same area or the same volume. By applying a positive voltage to the above-mentioned anode material in an electrolytic bath an oxide barrier layer with a thickness corresponding to the applied voltage will be formed (formation). This oxide layer acts as dielectric in an electrolytic capacitor. The properties of this oxide layers are given in the following table: After forming a dielectric oxide on the rough anode structure, a counter electrode has to match the rough insulating oxide surface. This is accomplished by the electrolyte, which acts as the cathode electrode of an electrolytic
Fluoride selective electrode is given by the Nernst equation: where: Martin S. Frant and James W. Ross Jr. Electrode for Sensing Fluoride Ion Activity in Solution. Science 23 December 1966:Vol. 154. no. 3756, pp. 1553 - 1555 Fluoride selective electrode A fluoride selective electrode is a type of ion selective electrode sensitive to the concentration of the fluoride ion. A common example is the lanthanum fluoride electrode. In the lanthanum fluoride electrode, the sensing element is a crystal of lanthanum fluoride LaF, doped with europium fluoride EuF to create lattice vacancies. Such a crystal is an ionic conductor by virtue of the mobility
