1.Name: Sodium nitrate Chemical formula: NaNO3 Formula weght:84.99 2.Property: (1) ordinary sodium nitrate: white little crystals or light yellow (2) dry powder sodium nitrate: non-caking, showing loose status. Density:2.257. It is liable to deliquesce, dissolved in water, soluble in liquid ammonia, slightly soluble in ethanol and glycerin, Melting Point:308. While being heated up to about 380 it will decompose and release oxygen and turn into sodium nitrite,as the heating goes 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, sulfur, sodium nitrate etc. 3. Usage:  it has been wildly used in the glass industry, dye, dynamite, metallurgy, machinery, ceramic etc. 4. Specification: (Technical Standards:GB/T4553-2002) Item Unit High G. First G. Qualified G.
