US Classification:

Abstract:

A flowable, non-caking aqueous slurry of sodium chlorate and sodium chloride having a weight ratio of sodium chloride to sodium chlorate between about 0. 55 and 0. 65, and, more preferably, about 0. 59, is described. The slurry contains a solid phase essentially entirely of sodium chloride. The slurries contain from about 28 to about 33% by weight sodium chlorate, from about 15 to about 21% by weight sodium chloride, and from about 45 to about 58% by weight water. The slurries are produced by forming an initial aqueous solution of sodium chlorate and sodium chloride containing from about 28 to about 50% by weight sodium chlorate and from about 0 to about 14% by weight sodium chloride and subsequently adding sufficient sodium chloride to obtain a slurry containing from about 28 to about 33% by weight sodium chlorate, from about 15 to about 21% by weight sodium chloride, and from about 45 to about 58% by weight water.

Abstract:

A film-coated cathode is provided for the electrolysis of alkali metal halide solutions in the substantial absence of chromium ions. The cathode comprises a conductive substrate, such as titanium, steel, iron, or alloys thereof, coated with an adherent, porous film of a substantially nonconductive material having an average coating thickness of less than about 10. sup. 3 microns. The nonconductive, film-forming material is further characterized as being chemically inert in the halate solution.
