Stable non-caking aqueous slurry of sodium chlorate and sodium chloride and method of making

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.
