Chemical formula: NaNO3
Formula weight:84.99
2.Property:
(1) ordinary sodium nitrate: white little crystals or light yellow
(2) dry powder sodium nitrate: white,non-caking, showing quick-sand
status.
Density:2.257. It is liable to deliquesce, dissolved in
water,soluble in liquid ammonia,slightly soluble in ethanol and
glycerin,Melting Point:271℃. While being heated up to about 380℃it
will decompose and release oxygen and turn into sodium nitrite,as
the heating going on, it will decompose into oxygen,nitrogen and
nitrogen oxide. It has strong oxidability and can cause combustion
explosion if being mixed with organic substance,sulphur, sodium
nitrate etc.
3.Usage:it has being wildly used in glass industry,
dye,dynamite,metallurgy,machinery,ceramic etc.
