Our team takes pride in delivering dependable products and services with a quality distinction in thermal energy storage & water-soluble fertilizer industries globally. Leveraging advanced chemical technologies and localized mineral reserves, we supply high-purity inorganic salts to clients in more than 40 countries, resolving supply chain constraints and facilitating ecological breakthroughs.
Discover Our OperationsCalcium Nitrate Tetrahydrate (CAS No: 13477-34-4), representing as Ca(NO₃)₂·4H₂O, is a highly soluble, crystalline inorganic salt vital to a multitude of modern processing environments. Known for its distinct monoclinic crystal configuration, this compound serves as a primary vehicle for delivering highly bio-available nitrogen and calcium ions simultaneously. Unlike anhydrous configurations, the tetrahydrate form boasts rapid dissolution metrics and an exothermic dissolution profile that renders it advantageous in liquid formulations, agricultural fertigation systems, and specialized industrial settings.
At Shanxi Vojin New Materials, we synthesize Ca(NO₃)₂·4H₂O through a meticulously controlled neutralization process, reacting high-purity nitric acid with calcium carbonate reserves under exact thermal conditions. The raw liquor undergoes advanced chemical purification to eliminate heavy metal residues (such as lead, arsenic, and cadmium) and insolubles before entering localized crystallization units. The resultant material exhibits a high solubility profile of 1290 g/L at 20°C, a controlled pH range of 5.0–7.0 in aqueous solutions, and an assay purity profile surpassing 99%.
The production of industrial and agricultural-grade nitrates is undergoing a major technological transformation. Our research and development center is actively working on anti-caking coatings that utilize bio-based surfactants, preventing lump formation during ocean transport without compromising dissolved purity. Furthermore, we are refining our synthesis loops to integrate green ammonia feedstock, aligning with carbon-neutral industrial objectives.
Global supply lines require partners capable of weathering raw material fluctuations and logistics disruptions. Shanxi Vojin New Materials maintains a resilient supply framework by utilizing localized coal-to-chemical synthesis routes in Shanxi Province, ensuring a steady supply of nitric acid. Coupled with automated storage facilities and dedicated logistics corridors to major ports (such as Tianjin and Qingdao), we offer global buyers predictable lead times, bulk containerized shipping, and specialized moisture-controlled packaging configurations.

Expert answers regarding chemical characteristics, storage, and application protocols for our Calcium Nitrate Tetrahydrate.
The tetrahydrate formulation contains four water molecules in its crystal structure (Ca(NO₃)₂·4H₂O), giving it a monoclinic crystalline structure that dissolves quickly and exothermically. Anhydrous versions lack water molecules, making them more hygroscopic but offering a higher concentration of calcium per unit of weight.
Due to its high solubility and hygroscopic properties, it should be stored in a cool, dry, well-ventilated warehouse. Keep containers sealed tightly. Use pallet storage, avoid high stacking heights to prevent pressure-caking, and keep away from incompatible materials like organic reducing agents.
Yes, all of our products conform to ISO 9001:2015 quality standards. For international shipments, we provide complete safety datasheets, compliance documentation (including EU REACH pre-registration where applicable), and third-party inspection certificates from SGS or BV.
Direct mixing in concentrated stock solutions should be avoided, as calcium ions react with phosphate and sulfate ions to form insoluble calcium phosphate or calcium sulfate (gypsum) precipitates. We recommend using separate stock tanks in hydroponic and fertigation systems.
