Description

Calcium Nitrate Hydrate 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 rapid nutrient delivery and improved plant cell wall strength. It is a critical raw material for manufacturers in the agriculture, wastewater treatment, and concrete industries. The compound is supplied under the identifier CAS NO 35054-52-5.

Application

• Fertilizer & Horticulture: A key ingredient in water-soluble fertilizers, hydroponic nutrient solutions, and foliar sprays to prevent calcium deficiencies like blossom end rot.
• Concrete & Construction: Used as a non-chloride accelerating admixture to speed up the setting time of concrete, especially in cold weather conditions.
• Wastewater Treatment: Employed as a nutrient source in biological wastewater treatment processes to enhance microbial activity and denitrification.
• Latex & Polymer Coagulant: Acts as a coagulating agent in the production of synthetic latex and other polymer dispersions.
• Refrigeration & Cold Packs: Utilized in endothermic reaction mixtures for portable cold packs and industrial refrigeration processes.
• Pyrotechnics & Explosives: Serves as an oxidizer in certain specialty pyrotechnic compositions and explosives manufacturing.

Quality Control

Our Calcium Nitrate Hydrate is produced under a stringent quality management system. Each batch is tested to ensure it meets precise specifications for purity, heavy metal content, and solubility. Certificates of Analysis (COA) documenting these results are provided with every shipment. We can supply grades suitable for agricultural, technical, and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic (moisture-sensitive) and strong oxidizing nature, keep the product away from moisture, heat, and combustible or reducing agents. Store separately from acids, organic materials, and finely powdered metals.
