Detailed Description:

Cas No. :7631-99-4

Molecular Formula ：NaNO3
CAS NO. ： 7631-99-4
HS Code： 3102500000
UN No： 1498
Hazard category： 5.1
EINECS NO.： 231-554-3

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 271℃. And decomposition temperature is 380℃. 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.

Usage: This product is an important chemical raw material, widely used in industry. The raw material is used in enamel, glass, food, inorganic salt, fertilizer, dye, metallurgy, machinery, medicine, cigarette, Kemeile, analytical chemistry, explosive fireworks, etc

Sodium nitrate can be used as raw material for the production of explosives, bitter acids, dyes and pharmaceuticals, as well as decolorizing agent, defoamer, flux, oxidant, metal cleaner, etc.
