Understanding the Chemistry and Performance of 5Ca(NO₃)₂·NH₄NO₃·10H₂O

The chemical compound 5Ca(NO₃)₂·NH₄NO₃·10H₂O (commonly known as Calcium Ammonium Nitrate Decahydrate double salt) represents a highly sophisticated complex crystal design. By binding calcium nitrate and ammonium nitrate in a specific stoichiometric ratio alongside precisely ten molecules of crystalline water, this compound exhibits unique thermodynamic and biochemical characteristics.

Unlike conventional mechanical mixtures, this double salt forms homogeneous, highly structured granules. The presence of the ammonium phase alongside nitrate nitrogen delivers a staged nutrient-release profile, while the high calcium concentration acts as a structural stabilizer for cell walls in agricultural systems, and as an effective precipitant and setting controller in industrial chemical synthesis.

In global commerce, sourcing high-purity 5Ca(NO₃)₂·NH₄NO₃·10H₂O requires partnerships with manufacturers capable of maintaining absolute control over crystallization temperature thresholds, heavy metal inclusions, and particle-size distribution.

Advanced Production & Technical Synthesis Roadmap

How modern Chinese chemical facilities achieve ultra-purity and anti-caking properties through crystal engineering.

1. Stoichiometric Synthesis

Supervised reaction of high-purity nitric acid with calcium carbonate (limestone) and gaseous ammonia. Exact temperature profiles are maintained to prevent side reactions and maintain stoichiometry.

2. Controlled Crystallization

Utilization of vacuum crystallizers ensures that the decahydrate form (10H₂O) binds uniformly without thermal breakdown of the ammonium nitrate components, avoiding unstable phase transformations.

3. Granulation & Anti-Caking

Implementation of fluid-bed granulation coupled with organic/inorganic surface-active coating. This guarantees free-flowing characteristics during global maritime shipment under tropical conditions.

Macro-Industry Solutions & Global Applications

Bridging pure chemistry with real-world economic sectors to drive process optimization and material longevity.

Modern Precision Agriculture

Technical & Commercial FAQ (Q&A)

Addressing core procurement questions, chemical properties, and storage logistics for professional buyers.

Is 5Ca(NO₃)₂·NH₄NO₃·10H₂O classified as an explosive substance for transport?
No. Unlike pure ammonium nitrate, the high concentration of calcium nitrate and crystallization water in the double salt 5Ca(NO₃)₂·NH₄NO₃·10H₂O renders it non-explosive. It is classified under IMDG rules as non-dangerous goods or Class 9/5.1 depending on specific national standards, ensuring lower logistics costs and simplified storage requirements.
What are the primary differences between this double salt and standard Calcium Nitrate?
Standard Calcium Nitrate (anhydrous or tetrahydrate) is highly hygroscopic and contains little to no nitrogen in the ammonium form. 5Ca(NO₃)₂·NH₄NO₃·10H₂O has a unique crystal structure containing a small fraction of ammoniacal nitrogen (~1.1%), which significantly improves mechanical prill strength, limits moisture uptake, and provides a dual-action nitrogen release.
How does Shanxi Vojin New Materials guarantee anti-caking during long-term maritime transit?
We coat the granules with specialized organic anti-caking agents and inorganic micro-silica layers. Combined with humidity-controlled production and double-layer moisture-proof packaging, this keeps the granules free-flowing even during long shipments across high-humidity equatorial oceans.
What is the solubility limit of this compound in water?
It is highly soluble in water, dissolving up to 1200 grams per liter at 20°C. Due to our rigorous filtration of insolubles (under 0.1%), the solution remains clear, preventing blockages in drip lines, hydroponic systems, and chemical injection equipment.
Can this compound be blended with other fertilizers?
Yes, it can be combined with potassium nitrate, ammonium nitrate, and urea. However, it should not be mixed directly with soluble phosphates (such as MAP or DAP) or sulfate-containing fertilizers (such as magnesium sulfate) in concentrated stock solutions, as this will lead to the precipitation of insoluble calcium phosphate or calcium sulfate (gypsum).
What are the lead times for bulk industrial orders?
For standard grades, we can ship within 7 to 15 days from receiving confirmed orders due to our 600,000-ton capacity. Customized formulations, special sizing requirements, or private labeling packaging may require 20 to 30 days for synthesis and line setup.
Does Vojin support industrial-grade testing for thermal energy storage (TES) systems?
Yes. We offer customized calcium double salts with ultra-low impurity profiles (low iron, low sodium, and low chloride) specifically designed for thermal energy storage systems. We provide comprehensive thermal analysis reports and work with research institutions globally.
