25 KG/BAG Sodium Nitrate CAS 7631-99-4 Formula NaNO3
Sodium nitrate is an inorganic compound. It is colorless, transparent rhombus crystals, or white or slightly yellow granules or powder at room temperature. It tastes bitter and salty, is easily soluble in water and liquid ammonia, slightly soluble in glycerol, and is easily deliquescent. Especially when it contains a very small amount of sodium chloride impurity, the deliquescent property of sodium nitrate is greatly increased. When dissolved in water, the temperature of the solution decreases and the solution becomes neutral. When heated, sodium nitrate is easily decomposed into sodium nitrite and oxygen.

1. Health hazard. Irritating to skin and mucous membranes. They have oxidized ferrous iron in blood to ferrous iron, which loses oxygen-carrying capacity. When ingested orally in large quantities, patients experience severe abdominal pain, vomiting, bloody stools, shock, convulsions, coma, and even death.
2. Explosion hazard. Strong oxidizing property, contact with organic matter or phosphorus and sulfur, friction or impact can cause combustion and explosion.
