High purity KNO3 With 99.9% / CAS No.7757-79-1 / Industrial grade
Potassium nitrate (chemical formula: KNO3) is the nitrate of potassium. It is a crystalline salt and a strong oxidizer which can be specially used in making gunpowder, as a fertilizer, and in medicine. It can be manufactured through the reaction between ammonium nitrate and potassium hydroxide, and alternatively through the reaction between ammonium nitrate with potassium chloride.
Structure type:
| Potential Exposure | Used to make explosives, gunpowder, fireworks, rocket fuel; matches, fertilizer, fluxes, glass manufacture; and as a diuretic |
| Shipping | UN1486 Potassium nitrate, Hazard Class: 5.1; Labels: 5.1-Oxidizer. |
| Purification Methods | It crystallises from hot H2O (0.5mL/g) on cooling (cf KNO2 below). Dry it for 12hours under vacuum at 70o. The solubility in H2O is 13.3% at 0o, 110% at 60o, and 246% at 100o. After two recrystallisations, technical grade salt had <0.001 ppm of metals. The fused salt is a powerful oxidising agent. |
| Incompatibilities | A powerful oxidizer. Dangerously reactive and friction-and shock-sensitive when mixed with organic materials and many materials. Violent reactions with reducing agents; chemically active metals; charcoal, trichloroethylene. |
