Description

Nitric Acid, Calcium Salt, Dihydrate is the dihydrate form of calcium nitrate, a highly soluble and versatile inorganic salt. This compound is valued for its dual role as a source of both calcium and nitrate ions, making it an effective nutrient and a key chemical intermediate. It is essential for manufacturers in the agriculture, chemical synthesis, and construction industries seeking a reliable, water-soluble source of calcium.

Application

• Fertilizer Production: A primary source of highly soluble calcium and nitrogen for specialty fertilizers and foliar sprays, correcting deficiencies in crops.
• Concrete & Construction: Used as a non-chloride accelerating admixture in cold-weather concrete pouring to reduce setting time.
• Wastewater Treatment: Acts as an odor control agent and a nutrient source in biological wastewater treatment processes.
• Chemical Synthesis: Serves as a precursor and oxidizing agent in the manufacture of other nitrate compounds and specialty chemicals.
• Latex Coagulant: Employed in the production of synthetic rubber and certain polymers as a coagulating agent.
• Heat Transfer Fluids: A component in some molten salt mixtures used for heat storage and transfer in industrial applications.
• Pyrotechnics & Explosives: Used in the formulation of certain pyrotechnic compositions and explosives as an oxidizer.
• Laboratory Reagent: Utilized in analytical chemistry and research as a standard or reagent.
