Calcium Nitrate

Description

1. Product Overview

Calcium Nitrate (Ca(NO₃)₂) is a highly soluble, dual-nutrient fertilizer and industrial additive, delivering readily available calcium and nitrate-nitrogen for precision agriculture and concrete acceleration. Its primary industrial use spans large-scale fertigation, hydroponic crop nutrition, and wastewater odor control, as well as set-accelerating admixtures in concrete manufacturing. The key value proposition is exceptional solubility (zero sediment), rapid nutrient uptake, and enhanced calcium bioavailability — directly translating to reduced crop disorders and improved infrastructure curing cycles. Strategically, it is indispensable for markets facing soil degradation and demanding higher-yield, climate-resilient agriculture, positioning it as a critical input for global food security and durable construction standards.

2. Key Specifications & Technical Characteristics

• Chemical composition: Calcium Nitrate tetrahydrate (Ca(NO₃)₂·4H₂O) – 100% water-soluble crystalline form

• Purity level: ≥99.0% (industrial/agricultural premium grade)

• Nutrient guarantee: Total Nitrogen (N) – 15.5% (as NO₃⁻) | Calcium (Ca) – 19% (as CaO equivalent)

• Physical characteristics: White, free-flowing prilled or granular (2–4 mm), non-caking with anti-caking coating, bulk density 0.9–1.1 g/cm³

• Insolubles: ≤0.1% – suitable for drip irrigation and micro-sprinklers

• Packaging options: 25 kg laminated woven bags (palletized), 500 kg FIBC big bags, or 1,250 kg bulk bags

• Shelf life: 24 months in original sealed packaging under dry, ventilated conditions (<40°C, ≤70% RH)

3. Core Industrial Applications

• Precision agriculture & fertigation: Direct injection into drip systems for high-value crops (tomatoes, peppers, apples, strawberries). Outperforms ammonium-based nitrates by eliminating root burn and enabling calcium transport to fruit trusses, reducing blossom end rot by up to 70% compared to calcium chloride alternatives.

• Hydroponic & greenhouse production: Preferred over calcium sulfate due to complete solubility and rapid pH neutrality; ensures uninterrupted nitrate‑nitrogen without ammonium toxicity in recirculating systems.

• Concrete acceleration & anti‑freeze: As a non‑chloride set accelerator (0.5–2% by cement weight) – superior to calcium chloride because it eliminates corrosion risk in rebar, while cutting cold-weather curing time by 30–40% versus standard admixtures.

• Wastewater & odor control: Suppresses hydrogen sulfide emission in collection systems and sludge treatment via nitrate‑driven biological oxidation – more cost‑effective than iron salts and safer to handle than peroxides.

4. Competitive Advantages

• Quality consistency: ISO 9001:2015 certified production with batch‑level ICP‑OES analysis; each shipment includes a Certificate of Analysis (CoA) verifying purity, insolubles, and particle size distribution.

• Supply reliability: Dedicated manufacturing lines with 50,000 MT annual capacity; safety stock held in three regional warehouses (Rotterdam, Singapore, Houston).

• Logistics capability: Bulk vessel, break‑bulk, or containerized LCL/FCL; lead times as short as 7 days for stocked origins.

• Price competitiveness: Direct sourcing from integrated nitrates complex – eliminates 2–3 intermediaries, delivering 8–12% cost savings compared to repackaged European or Chinese spot offers.

• Sustainability: Zero‑effluent production process; low‑carbon nitrate synthesis with 35% less CO₂ per MT than traditional ammonia‑based methods.

• Technical support: Access to application guides (fertigation rates, concrete dosage tables) and on‑call agronomist/chemist support for procurement teams.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 MT (bulk or equivalent in bags)

• Loading capacity per container: 25 MT per 20′ dry container (palletized big bags) or 27 MT per 20′ open‑top container (bulk liner)
