was maintained by adjusting the brine flow rate with brine flow control 52 additional chemicals sodium dichromate na 2 cr 2 o 7 for example were added through chemical inlet 54 fig2 4 graphically present the test results fig2 shows a stable rate of sodium chlorate production throughout the test duration fig3 shows that the off gas generated by the electrolytic cell was about 1 5 oxygen during the test period moreover fig4 shows the stability of the voltage during the test period in summary the test cell producing sodium chlorate performed steadily with no or minimal passivation for over 80 days and generating on the average was about 1 5 oxygen and with sufficient voltage stability at about 3 3 v the electrode prepared according to example 1 was evaluated as an anode in an accelerated anode aging test cell similar to the one described in example 2 and schematically illustrated in fig1 in this example the service life or lifetime of the electrode coating prepared in example 1 was compared against the service life or lifetime of commercially available electrode coatings under accelerated wear conditions the test system was continuously operated under the following conditions in the beginning of each accelerated wear test the test cell was run in a galvanostatic mode at 3 9 a when the cell voltage of 4 5 v was reached the test was switched into a potentiostatic mode.
