Molecular Formula: Ca(NO3)24H2O, Molecular Weight: 236.149Physicochemical Properties: calcium nitrate tetrahydrate is a white columnar shape crystal of monoclinic system including α and β crystallographic form. Specific Density: 1.82, Melting Point: 39.7C. It decomposes at 40C or so, and converts into anhydrous calcium nitrate due to thorough dehydration when heated at 151C. When heated furthermore to 500C, calcium nitrate will first break down to calcium nitrite accompanied with oxygen gas emitting, then degrade to calcium oxide and nitrogen oxide. The product is apt to dissolve in water, methanol, ethanol, acetone, methyl acetate and liquid ammonia. The calcium nitrate is used as an oxidizer with hygroscopic property, resulting in extreme deliquescence in air.Inspection Item Ind.G.
