Sodium Nitrate 25kg Bag Industrial Used 99%Min for Glass Making CAS No 7631-99-4
Name: Sodium Nitrate
Molecular Formula: NaNO3
Molecule Weight: 84.99
CAS NO.: 7631-99-4
Appearance:White or light yellow Fine Crystal
Property:White fine crystal. Some are light gray or buff. The relative molecular weight is 84.99 and density is 2.257. It's easy to be deliquescence and to dissolve in water and liquid ammonia, but only a little can dissolve in ethanol and glycerin. The melting point is 271ºC. And decomposition temperature is 380ºC. Its decomposition products are sodium nitrite and oxygen. If heated to higher temperature, it will be decomposed into the mixed gas of oxygen, azote and oxynitride. It has the strong oxidizing property and can cause the inflammation and explore while mixed with organics, sulfur and sulfite etc.
