Anodic electrodes for ozone generation were prepared with lead dioxide particles of various diameters. The lead dioxide particles were characterized with X-ray diffraction analysis, and the electrodes were characterized and performed for ozone generation. It was revealed that both the diameters of the lead dioxide particles and the contents of the pore forming agent have great effect on the performance of the electrodes. With decreasing of the diameters of the lead dioxide particles from the range of 55–74 µm to the range of 15–35 µm, the performance of the electrodes improved. But no further improvement was found with further decreasing of the particle diameters to the range of 5–15 µm. However, by employing an appropriate amount of pore forming agent during the electrode preparations, the performance of the anodic electrode can be improved. The optimized weight ratio of ammonium oxalate to lead dioxide is 1.33/100.
