Anode Fabrication for Electrochemical Waste Water Treatment
How tin-oxide doped with antimony can be coated over a noble metal (like Titanium)/Ceramic (like Ebonex). This is required for electrochemical oxidation (anodic oxidation) of wastewater. Commercial information like source for availability of such powder, vendors for coating such powder or ready made electrode(of such type) suppliers will be of great help. Thanks in advance.Shanu kumar Jain

Most of these processes are covered under both US, European, and other foreign patents, so the likelihood of anyone providing this information to you non-commercially (without remuneration) is very low.
Depending on the desired outcome for the process you are trying to accomplish, there may be several other types of coatings that might work. The existence of several anions in certain wastewater streams can be detrimental to the anodes, such as fluorides, chlorides, and others. In most of these cases, the coating on the anode is not what is attacked - its the substrate. Oxide coatings are almost always thermally applied, using an organic solution containing dissolved metal halide complexes, where the solution is thermally decomposed leaving the resultant metals. These coatings are micro-cracked - meaning they have lots of cracks in them that expose the substrate. This is caused by the expansion of the substrate while heating, and the resultant cracking that occurs when they cool.
