Abstract

An electrolyzer for the production of sodium chlorate (NaClO.sub.3) from brine, the electrolyzer having four basic components: an electrolysis cell, a reactor, a heat exchanger, and a means for circulating the brine in a loop from the electrolysis cell, to the reactor, the heat exchanger, and back to the electrolysis cell, the electrolysis cell comprising electrically conductive pieces and non-conductive pieces with such pieces being randomly intermixed and spaced between two electrical contacts located in a cavity, the proportion of conductive to non-conductive pieces being sufficient to form strands or clumps of conductive pieces but less than the ratio which causes an electrical shunt between the electrical contacts.
