COMMERCIAL GRADE POTASSIUM NITRATE GRADE B (GOST 19790-74)

Potassium nitrate (KNO3 ) is crystalline powder of white colour sometimes slightly yellowish/greyish. It is readily soluble in water. It is used in various sectors in industry and agriculture: as a component of some gun powders and pyrotechnic compositions; in glass industry for crystal glass decolorization and clarification, for glassware reinforcement; in production of enamels, thermal salts and heat-transfer agents; in metallurgy for metal hardening; as valuable undiluted fertilizer containing two nutrient elements.
