TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The solid-chemical composition further comprises (wt.%) another complex inorganic phosphate (0.1 - 15), source of inorganic nitrogen (0.1 - 5), ammonium-free source of inorganic nitrogen (0.1 - 5), simple inorganic orthophosphate (0.1 - 20), another organic disintegrant (0.01 - 1), inorganic disintegrant (0.01 - 10 or 0.05 - 10), inorganic buffer (0.5 - 30), metal catalyst for chemical-oxidation reactions (0.25 - 15), another lubricant (0.01 - 1). The composition is prepared in the form of granules, briquettes, tablets, capsules and/or pellets.Preferred Component: The another complex inorganic phosphate is selected from at least one sodium tripolyphosphate, sodium-potassium tripolyphosphate or tetrasodium polyphosphate. The ammonium-free source of inorganic nitrogen is selected from at least one sodium nitrate, sodium-potassium nitrate, potassium nitrate or other soluble salts of nitrate. The simple inorganic orthophosphate is selected from at least one sodium phosphate, calcium phosphate, potassium phosphate or sodium-potassium phosphate. The inorganic disintegrant is selected from at least one bentonite, montmorillonite, kaolinite or other clay minerals. The inorganic buffer is selected from at least one calcium carbonate, lime, limestone, siderite and ferrous carbonate, rhodochrosite and manganese carbonate, calcium phosphate, sodium bicarbonate, portland cement, metal oxides, metal hydroxides, or metal oxyhydroxides. The metal catalyst is selected from at least one ferrous sulfate or other soluble salts of ferrous iron. The another lubricant is selected from at least one calcium stearate and other stearates, stearic acid, sodium stearyl fumarate, hydrogenated vegetable oil, silicone, talc, and corn starch.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The another organic disintegrant is selected from at least one powdered molasses, granulated sugar, sodium starch glycolate, crosscarmelose of sodium, or crospovidone.
