Explore our premium-grade inorganic chemicals, including nitrates, water-soluble fertilizers, and chemical compounds engineered for absolute purity and stability.
A rigorous review of chemical specifications, global supply chain structures, and macroeconomic vectors driving calcium nitrate utilization in modern industry.
Calcium Nitrate, commonly represented by the formula Ca(NO3)2 (and often distributed in various hydrated states like the tetrahydrate form Ca(NO3)2·4H2O or anhydrous/double salt versions containing ammonium nitrate), is one of the most critical compound chemical agents across the modern agricultural, construction, and water-treatment industries.
In recent years, the chemical processing industry has experienced a paradigm shift towards highly pure, low-heavy-metal variants—often referenced inside global purchasing lists as Tata Calcium Nitrate or similar premium commercial designations. As the demands for precise chemical ratios inside large-scale hydroponics, state-of-the-art concrete formulations, and thermal energy storage materials increase, partnering with a primary chemical synthesis factory in China becomes essential to secure consistent, high-yield supply chains.

For enterprise purchasing managers, sourcing directly from a vertically integrated manufacturer like Shanxi Vojin New Materials Co., Ltd. allows for precise customization of these parameters. By maintaining direct control over raw chemical lines, we can adjust the ammonia-to-calcium ratio, control trace element dosing, and prevent mechanical caking through advanced post-processing treatments.
Discover how Tata Calcium Nitrate functions as a primary driver of efficiency and stability across multiple specialized sectors.
High-purity molten salts are vital in concentrated solar power (CSP) facilities. We synthesize low-sodium, low-chloride mixtures optimized for thermal cycling, ensuring maximum operating life of industrial molten salt loops.
Our ultra-pure nitrates are deployed as clarifying and cleaning agents in specialized glass, LED substrate processing, and optical materials requiring strict trace element containment.
Serving as a catalyst promoter, concrete accelerant, and chemical scrub solution in industrial boilers and flue gas desulfurization systems to control emissions and enhance thermal efficiency.
Highly soluble calcium nitrate supplies essential nutrients to crops without modifying soil pH. Perfect for high-frequency drip irrigation, prevention of physiological disorders (e.g. blossom-end rot), and increasing post-harvest storage stability.
Driven since 2000, we have been committed to the entrepreneurial spirit and passion for innovation. Our team takes pride in delivering dependable products and services with a quality distinction in thermal energy storage & water-soluble fertilizer industries globally.
Our main plant is nestled in Shanxi, the chemical energy heartland of China, allowing us to leverage direct access to high-grade industrial raw materials. With over two decades of technical evolution, we control the entire processing loop—from initial synthesization of raw nitrate mixtures to precision bagging, palletization, and custom logistics management.

The commercial production of high-grade calcium nitrate at the Shanxi Vojin facility utilizes the neutralization method between nitric acid (HNO3) and high-purity limestone (CaCO3), as depicted by the equation:
CaCO3 + 2HNO3 → Ca(NO3)2 + CO2↑ + H2O
Our technical roadmap focuses on addressing two major pain points in standard production: hygroscopic caking and heavy metal contamination.
As global policies align under carbon-neutral regulations (such as Europe’s CBAM), Shanxi Vojin is integrating green-hydrogen-derived ammonia for our synthesis lines. By scaling up low-carbon nitric acid processes, we aim to lower the carbon footprint of our calcium nitrate products by 30% by 2028. This ensures that our global supply chains comply with future environmental standards, giving import buyers a distinct advantage in compliance.
Why leading global distributors and agricultural enterprises establish long-term procurement contracts with Shanxi Vojin.
Our integrated operations and decades of exporting ensure consistent product quality, clear custom declarations, and secure logistics.
An annual output of 600,000 tons of high-grade molten salts, nitrates, and fertilizers guarantees supply stability for large orders.
Experienced technical engineers and sales teams respond quickly to resolve customization requests, supply chain challenges, and compliance inquiries.
We offer a broad range of nitrate formulations including KNO3 and NaNO3 to meet diverse agricultural and industrial requirements.
How we mitigate transport risks, maintain continuous production, and ensure full compliance with regulatory frameworks worldwide.
For international buyers purchasing agricultural or industrial chemicals in bulk, freight costs and loading delays represent significant risks. Located in Shanxi, we are close to China's main coal and raw nitrogen deposits, protecting us from raw material shortages.
Our logistics division utilizes rail and road links to major northern ports, primarily Tianjin Port and Qingdao Port. This dual-port access allows us to avoid port congestion and maintain weekly shipping schedules to regions including North America, Europe, Latin America, and Southeast Asia.
Compliance is essential when importing chemical products. Shanxi Vojin operates in strict compliance with safety, environmental, and quality management systems:

When stored in its original, unopened packaging in a cool, dry, and well-ventilated warehouse, industrial-grade calcium nitrate has a shelf life of approximately 24 months. Because calcium nitrate is highly hygroscopic, it absorbs moisture from ambient air. Storage temperature should remain below 30°C (86°F), away from direct sunlight, open flames, and combustible organic compounds. Stack pallets at a maximum of two layers to prevent compression-induced caking.
Calcium nitrate acts as a set accelerator by promoting the hydration of tricalcium silicate (C3S), a primary mineral phase in Portland cement. The calcium ions (Ca2+) lower the dissolution barrier of silicate species, accelerating the precipitation of calcium silicate hydrate (C-S-H) gel. This results in faster initial and final setting times, which is useful for cold-weather concreting. It also helps prevent corrosion of steel reinforcements in concrete.
The difference lies in the chemical formulation and nitrogen distribution. Standard calcium nitrate (typically 19% Ca, 15.5% N) consists primarily of calcium nitrate double salt containing a small amount of ammonium nitrate. Calcium Ammonium Nitrate (CAN) is a mixture of ammonium nitrate and crushed calcium carbonate (limestone). CAN generally has a higher nitrogen concentration (typically 26% N or 27% N, half ammoniacal and half nitric) but exhibits lower solubility and lower immediate calcium availability compared to pure, fully soluble calcium nitrate.
We ensure quality by managing the entire manufacturing process, from sourcing raw nitric acid and limestone to final packaging and testing. Operating since 2000, our facility features an on-site laboratory for ICP-OES spectroscopy and wet chemical analysis. Every shipment is issued a batch-specific Certificate of Analysis (COA) detailing physical and chemical parameters, ensuring compliance with international regulations (e.g., EU REACH, ISO 9001).
Yes. In municipal and industrial wastewater systems, anaerobic conditions can cause sulfate-reducing bacteria to produce hydrogen sulfide (H2S) gas, which is toxic and corrosive. Dosing calcium nitrate provides a source of oxygen for nitrate-reducing bacteria. These bacteria consume organic carbon, preventing the reduction of sulfates and eliminating the production of H2S gas.
We work closely with global industry leaders, distributors, and logistics partners to ensure prompt and secure deliveries.
