I have been doing experiments trying to make solid lead anodes with lead dioxide formed on the surface for the production of Chlorate/perchlorate. I continue to have problems with the coating "flaking off" after an extended time. Meanwhile, I want to make some perchlorate! I have been looking at various anodes and noticed platinized titanium anodes on Ebay. Does anyone know about these? I am certain the platinum coating on these anodes is very thin and am concerned with the coating failing. Many years ago, I worked in the lab at an electroplating company and was put in charge of the operation and maintenance of a device which removed chrome out of rinse water by way of a semi-permeable membrane and electrolysis. This device had platinized titanium electrodes and I distinctly remember the platinum peeling off those electrodes (much to the dismay of my boss, who had authorized the $15,000 purchase of that device.) I am wondering if it is possible that a new technique has been developed which makes these anodes more durable?
