potassium nitrate water soluble fertilizer,
nitrate of potash fertilizer
99.9 % potassium nitrate / 100% water soluble / CAS No. 7757-79-1
Poison by intravenous route. Moderately toxic by ingestion. An experimental teratogen. Experimental reproductive effects. Mutation data reported. Ingestion of large quantities may cause gastroenteritis. Chronic exposure can cause anemia, nephritis, and methemoglobinemia. When heated, reaction with calcium hydroxide + polychlorinated phenols forms extremely toxic chlorinated benzodtoxins. A powerful oxidizer. Gunpowder is a mixture of potassium nitrate + sulfur + charcoal. Explosive reaction with aluminum + barium nitrate + potassium perchlorate + water (in storage), boron + laminac + trichloroethylene. Forms explosive mixtures with lactose, powdered metals (e.g., titanium, antimony, germanium), metal sulfides (e.g., antimony trisulfide, barium sulfide, calcium sulfide, germanium monosulfide, titanium disulfide, arsenic disulfide, molybdenum disulfide), nonmetals (e.g., boron, carbon, white phosphorus, arsenic), organic materials, phosphides (e.g., copper(l1) phosphide, copper monophosphide), reducing agents (e.g., sodium phosphinate, sodium thiosulfate), sodium acetate. Can react violently under the appropriate conditions with 1,3- bis(trichlorometh~d)benzene, boron phosphde, F2, calcium shcide, charcoal, chromium nitride, Na hypophosphte, ma2O2 + dextrose), red phosphorus, (S + As2S3), thorium dicarbide, trichloroethylene, zinc, zirconium. When heated to decomposition it emits very toxic fumes of NOx and K2O. See also NITRATES.
