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. Used
in waste water pre-conditioning. Used in set accelerating concrete admixtures.
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.
