Strontium Nitrate
Chemical Name: Strontium Nitrate
Synonyms: Strontium Nitrate Hexahydrate
CAS No.: 10042-76-9
Relative molecular mass:211.63
Molecular Formula: Sr(NO3)2
Colorless crystallization or white podwer, relative density: 2.986. Melting point: 570℃. Easily dissolve in water, liquid ammonia, slightly soluble in anhydrous alcohol and actone. Decompose to emit oxygen by heating and become strontium nitrite, emit nitrogen monoxide and 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.
