99.5 % strontium nitrate 

 Physicochemical Properties:

 Colorless crystallization or white powder, relative density 2.986.Melting point 570 . Easily dissolve in water, liquid ammonia, slightly soluble in anhydrous alcohol and acetone. Decompose to emit oxygen by heating, and become strontium nitrite, emit nitrogen monoxide and nitrogen dioxide to produce strontium oxide by further heating. As oxidant, it will cause combustion and explosion if contacts, rubs, hits with organic matters or meet fire, and burst into carmine flame. Venomousness!

Applications and Usages:

Used for making red firework; signal lamp of sea-route, railway and aerodrome; signal shell, flame tracer and flame tube in national defense industry. Also used as aluminiferous agent of making television kinescope and optical glass. Still used in medicine and manufacture of fluoroph.
