Description

Calcium Nitrate is a highly soluble inorganic salt that serves as a vital source of both calcium and nitrate nitrogen. This dual-nutrient profile makes it an essential compound for promoting plant growth and strengthening cellular structures in various industrial and agricultural processes. It is a key material for manufacturers and suppliers in the fertilizer, wastewater treatment, construction, and chemical synthesis sectors seeking a reliable and efficient source of bioavailable calcium.

Application

• Fertilizers & Horticulture: A premium component in water-soluble and foliar fertilizers, providing readily available calcium and nitrogen to correct deficiencies and prevent disorders like blossom-end rot in fruits and vegetables.
• Concrete & Construction: Acts as a powerful set accelerator and anti-freeze admixture in concrete, allowing for cold-weather pouring and improving early strength development.
• Wastewater Treatment: Used in odor control and biological nutrient removal processes, particularly for preventing hydrogen sulfide formation in sewer systems.
• Chemical Manufacturing: Serves as a raw material or intermediate in the production of other nitrate compounds, explosives, and specialty chemicals.
• Latex Coagulant: Employed in the rubber and latex industries for the coagulation of dipped goods like gloves and balloons.
• Refrigeration: Utilized in phase-change materials and as a component in some refrigeration brines.
