Different and exotic anodes for chlorate production

symboom - 18-4-2011 at 18:51

anodes
-->Tungsten Carbide drill bit i know tungsten metal will not make chlorate under any condition not sure if the carbide compound will.because carbon makes chlorate

-->a solution of Bismuth subsalicylate formed and electroplating bismuth on an anode like copper or silver from wires for it does not oxidize to easily then electroplating manganese dioxide on top of the bismuth

-->silicon for an anode not sure how that will work
which silicon can come from a little solar panel from a calculator
take off the glass and leave exposed silicon

-->Tin Oxide doped with Bi Oxide is stated to be useful for Perchlorate my idea: tin plated can dipped in molten bismuth
then bismuth already forms an oxide surface layer upon cooling
then anode is ready

Interesting. Surely if you use semiconductor electrodes, your circuit resistance will be higher. Therefore what you save in electrode costs you pay for in running costs and efficiency.

tungsten carbide

actually low electrical resistivity (~2×10−7 Ohm·m)
and moderately costly
interesting WC has been investigated for its potential use as a catalyst and it has been found to resemble platinum in its catalysis of the production of water from hydrogen and oxygen at room temperature

I was talking about silicon's (a semiconductor) resistivity.

Didn't know that WC had such a low resistivity, thanks for pointing that out.

how about a plasma annode ?

run a big fat arc into the electrolyte

there's no need for that comment i am tiring to find alternatives from expensive or toxic anodes (as cobalt containing and lead dioxide) and also i said computer hard drives because through research and dissolving a hard drive platter in Aqua Regia and precipitating out a little bit of platinum they do in fact have a coating of platinum its not much

you right semi conductor can be used less effective more of the resistance would more go to heating water in the cell but it is an idea how cheap solar powered calculators cost
