We are professional manufacturer of Inorganic and Organic chemicals. Our products include Potassium Hydroxide, Calcium Nitrate, Antimony Oxide, Antimony Trioxide, Potassium Nitrate, Pentaerythritol, Iron oxide, Carbon Black, Potassium Hydroxide, EVA Resin, DBDPO and so on. Description: Molecular formula: Ca(NO3)2� 4H2O Molecular weight: **6.**9 Physicochemical Properties: Calcium nitrate tetrahydrate is a white columnar shape crystal of monoclinic system including a and crystallographic form. Specific Density: 1.*2, Melting Point: *9.7� C. It decomposes at *0� C or so, and converts into anhydrous calcium nitrate due to thorough dehydration when heated at **1� C. When heated furthermore to **0� C, 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. Applications and Usages: 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 also is applied in producing readily available fertilizer in agriculture. Packing: *5kg weaving bag with plastic liner or according to the requirements of customers.
