Sodium Nitrate

Other names: Caliche, Chile saltpeter, Nitrate of soda, Nitratine, Peru saltpeter, Soda niter, cubic niter
Molecular Formula: NaNO3
Molecule Weight: 84.99
CAS No.: 7631-99-4

Sodium nitrate is a kind of white or yellowish fine crystal with molecular weight of 84.99 and density of 2.257g/cm3. Its melting point is 271℃ and decomposition temperature is 380℃. It is hygroscopic and can be dissolved in water and ammonia solution easily, but less dissolvable in ethanol and glycerin. Its decomposition products include oxygen and sodium nitride. When heated to a higher temperature, the chemical compound can be decomposed into oxygen, nitrogen and oxynitride. Due to strong oxidizing property, sodium nitrate may cause inflammation and explosion when mixed with organics, sulfur, sulfite, etc.

Sodium nitrate is an important chemical material widely applied in industries such as glass making, dyeing, gunpowder, metallurgy, vitreous enamel, and more

    1. Sodium MetabisulphiteSodium metabisulphite is an inorganic compound in white or light yellow crystal powder. It offers a strong smell of sulfur dioxide, and its relative density is 1.4g/m3. The free flowing substance is easy to dissolve in water and glycerin-water solution. It has acidity. When the ambient temperature rises, sodium metabisulfite offers better solubility and is soluble in ethanol.
    1. Sodium NitriteThe sodium nitrite is an inorganic compound in white or light yellow fine crystal, without any smell but with slightly saline taste. It is hygroscopic and very soluble in water. It comes with molecule weight of 69.0 and density of 2.168 g/cm3. Its melting point is 271℃ and decomposition temperature is 320℃. Due to strong oxidizing property, it can be slowly oxidized into sodium nitrate, NaNO3.
