Calcium hypochlorite compositions that are classified as a Packing Group III Division 5.1 oxidizer material or as a non-Division 5.1 oxidizer material are described. In one embodiment, the compositions comprise an admixture of particulate calcium hypochlorite and particulate metaboric acid. The calcium hypochlorite is present in the composition in an amount and is of a concentration such that the composition would be classified as a Packing Group II Division 5.1 oxidizer in the absence of said particulate metaboric acid. Other embodiments described are solid shaped articles, e.g., tablets, comprising the described calcium hypochlorite-metaboric acid composition.

The invention discloses a snow melting agent, and belongs to the technical field of composite salt. Water and one, two, three, four, or five of calcium chloride, magnesium chloride, potassium chloride, sodium chloride, calcium nitrite, calcium hypochlorite, and urea chemical raw materials, a a water quality stabilizer, one, two, three, four, or five of sodium citrate, sodium hexametaphosphate, sodium gluconate, polyaspartic acid and other chemical materials as a corrosion inhibitor, one, two, three, four, or five of chemical fertilizers for promoting plant growth, potassium fulvate for improving a soil aggregate structure, and sodium chloride and activator urea for alleviating pavement thermal shock are used for forming the snow melting agent according to respective attributes.

The invention relates to a method for improving metallurgical performance of sintered ore. The method comprises the following steps: performing first-time uniform mixing and second-time mixing pelleting on sintering raw materials and fuel to form a sintering mixed material, wherein calcium chlorate is added in the sintering mixed material during first-time uniform mixing and second-time mixing pelleting to obtain a sintering mixed material A, a sintering mixed material B and a sintering mixed material C, and the calcium chlorate is added in a form of a saturated solution; and taking the sintering mixed material A as a bottom layer sintering material, taking the sintering mixed material B as a middle layer sintering material, taking the sintering mixed material C as an upper layer sinteringmaterial, igniting and drafting after adding all the three sintering mixed materials to perform sintering to obtain a finished product sintered ore. The calcium chlorate is added in the sintering mixed material, the calcium chlorate is heated and decomposed to release oxygen, so that the content of oxygen in the sintering material layer can be increased, the proportion of calcium ferrite in the sintered ore is increased, and the reducing property and the softening-melting and dropping property of the sintered ore are improved; meanwhile, the formed calcium chlorate is attached to the sinteredore uniformly, so that the low-temperature reducing pulverability of the sintered ore is improved.
