The Chlorates and Perchlorates
are various ways to manufacture the Chlorates and
Perchlorates, the most usual being electrolysis. The key component
is the Anode. Useful Anodes for making Chlorate and Perchlorate are Platinum and Lead Dioxide. Anodes that
make Chlorate ONLY are Graphite,
Mixed Metal Oxide (MMO), Magnetite, Manganese Dioxide and possibly Cobalt Oxide.
Electrolysis consists of passing a DC electric current between an Anode (+) and a
Cathode (-) in a water solution of the starting salt. Various Oxidation reactions take place
at the surface of the Anode. Various Reduction reactions take place at the Cathode. In a Chlorate cell some reactions also take place in the bulk of the solution, the end result being a range of substances plus your desired Chlorate or Perchlorate which must be
separated out and purified. There is a huge amount of information in Patents,
books and the scientific literature describing both Chlorate and Perchlorate cells and
processes used to make Anodes that may be viable for the Amateur. Most of this information
is not geared toward the Amateur and very often deals with aspects of the process
which are not of immediate interest to the Amateur but are very important to large
scale manufacturers or the scientist, eg. power efficiency, Tefal plots, possible/actual
reaction mechanisms etc. The biggest hurdle for the Amateur is obtaining
an Anode which is cheap, easy to obtain, and long lasting. This web page describes
ways to obtain Anodes and how to use them in the manufacture of Chlorates and Perchlorates.
