Properties: calcium nitrate tetrahydrate is a white columnar shape crystal of monoclinic system including α and β crystallographic form. 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.

[Use] It is mainly used as flocculant in rubber latex and refrigerant. And it is also employed in oil exploratory well and sewage treatment, etc. In agriculture it is used as soils culture and fast-effective fertilizer for acid soil. It also can be used to make fireworks and incandescent lamp chimney in light industry, to produce explosives in national defense industry and to paint negative pole in electron instrument industry. It is also a raw material in making other nitrates
Packaging: Plastic woven bag with PE inner 25kg/ 50kg/ 500kg/1000kg net bag.
[Storage e and transportation]It should be stored in a cool and dry house. The package must be sealed up and protected from moisture. Avoid mixing with organic compound or sulphur during storage and transportation. Prevent the material from rain and insolation. Load and unload carefully. In the case of a fire, use water, soil or other fire extinguishing media but aqueous solution must be prevented to flow towards inflammable materials.
