Description

Calcium Nitrate Trihydrate 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 component in formulations requiring efficient plant nutrition and rapid nitrate delivery. It is a cornerstone material for the agriculture, wastewater treatment, and construction industries, where its solubility and ionic properties are leveraged for growth enhancement, nutrient recovery, and concrete acceleration. CAS NO 15842-29-2.

Application

• Fertilizer & Horticulture: A key ingredient in water-soluble fertilizers, foliar sprays, and hydroponic nutrient solutions for fast-acting nitrogen and calcium to prevent blossom-end rot and improve crop quality.
• Concrete Admixture: Used as a non-chloride, corrosion-inhibiting accelerator to reduce setting time and enhance the early strength development of concrete, especially in cold weather.
• Wastewater Treatment: Employed as a nutrient source in biological denitrification processes to facilitate the removal of nitrates from industrial and municipal wastewater.
• Latex Coagulant: Acts as a coagulating agent in the production of synthetic rubbers and latex products.
• Refrigerant & Heat Transfer Fluid: Utilized in phase-change materials and as a component in certain refrigeration brines due to its favorable thermal properties.
• Chemical Synthesis: Serves as a precursor or calcium source in the manufacture of other calcium compounds, phosphors, and specialty chemicals.

Quality Control

Our Calcium Nitrate Trihydrate is manufactured under strict quality management protocols to ensure batch-to-batch consistency and reliability. Production adheres to relevant industrial and agricultural-grade specifications. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metal content, and insoluble matter are provided with each shipment to guarantee product integrity for your application.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after initial use to prevent moisture absorption and caking.
