Commodity: Calcium nitrate
Molecular formula : Ca(NO3)2·4H2O
Properties: white columnar shape crystal of monoclinic
system. Specific Density: 1.82. Melting Point: 39.7°C. It converts into anhydrous calcium nitrate due to thorough dehydration when heated at 151°C. When heated furthermore to 500°C, calcium nitrate will first break down to calcium nitrite accompanied with oxygen gas emitting, then degrade to calcium oxide and nitrogen oxide. It is apt to dissolve in water, methanol, ethanol, acetone, methyl acetate and liquid ammonia.
Packing: 25kg weaving bag with plastic liner or according to the requirements of customers.
Applications: It is mainly used as refrigerant and cement anti-freezer, phosphorizing agent in steel industry, as well as in manufacture of fireworks and other nitrates. It is applied in producing readily available fertilizer in agriculture. It is also used as an oxidizer with hygroscopic property, resulting in extreme deliquescence in air.
