ABSTRACT:
Rounded granular calcium hypochlorite comprised of a core of calcium hypochlorite encapsulated with a plurality of rounded layers of calcium hypochlorite, wherein the core of each particle generally has a diameter which ranges from about 200 to about 2,000 microns and the novel coated granules have a diameter ranging from about 400 to about 5,000 microns. Each layer is formed from an aqueous slurry of calcium hypochlorite which contains a high percentage of soluble inorganic salts as well as calcium hypochlorite. These soluble salts impart a high degree of cohesive bonding as each layer is formed and result in rounded granules of higher density and improved dust resistance.
