The steel melting process is thought as oxidation-reduction phenomena done by controlling the oxidising power of molten slag. So, if this oxidising power of molten slag could be measured in the course of melting, the steel melting process would be improved. The author intended to measure it electrochemically. In the first report, it is explained that the oxidising power of molten slag is the oxidising potential of molten slag, and it will be measured by measnring the oxygen activity in molten slag. From this point of view, the potential difference of a cell "pt I/slag I/slag II/pt II" was measured and this potential differenee reversibly changed according to the change of oxidising potential of the "slag I." Therefore, if for the half cell of "slag II/pt II, " another standard half cell could be placed, like hydrogen gas electrode in water solution, the oxidising power of the "slag I" would be measured with platinum electrode. For this standard half cell, molton silver saturated with oxygen was tried in this report. At first the potential difference of a cell "Ag/slag/Ag" was measured, and recognized that it was available as a standard half cell. So the potential difference of a cell "pt/slag/Ag saturated with O_2" was measured and recognized that this potential difference reversively changed according to the change of the activity of the oxygen in the molten slag, and that the oxidising power of the molten slag could be measured.
