Calcium Nitrate

Description

1. Product Overview
Calcium Nitrate (Ca(NO₃)₂) is a high-purity, water-soluble fertilizer and industrial additive, essential for precision agriculture and concrete acceleration. Its primary industrial use lies in delivering bioavailable calcium and nitrate nitrogen to crops in fertigation systems, while also serving as a chloride-free set-accelerator in construction. The key value proposition is dual: maximizing crop yield and quality under stress conditions, while enabling rapid, cold-weather concrete setting without corrosion risk. Strategically, it is indispensable for growers transitioning to controlled-environment agriculture and for infrastructure projects demanding faster turnaround—directly addressing global food security and construction efficiency challenges.

2. Key Specifications & Technical Characteristics

• Chemical composition: Calcium Nitrate tetrahydrate (Ca(NO₃)₂·4H₂O) – total N: 15.5% (nitrate form), CaO: 26.3% (calcium oxide equivalent)

• Purity grade: Technical grade ≥98.5% (agri/industrial); optional reagent grade (99.9%) for specialty applications

• Physical characteristics: White, free-flowing granular or crystalline powder; hygroscopic; bulk density 0.9–1.1 g/cm³; 100% water-soluble

• Packaging options: 25 kg laminated multi-wall paper bags, 500 kg FIBC big bags, 1,250 kg heat-sealed jumbo sacks; custom moisture-barrier liners available

• Shelf life: 24 months when stored in original sealed packaging in dry, ventilated conditions below 40°C

3. Core Industrial Applications

• Precision agriculture & hydroponics: Primary industries – high-value crops (tomatoes, peppers, apples, lettuce). Prevents blossom end rot and tip burn; supplies nitrate nitrogen for immediate uptake without root burn. Outperforms ammonium-based fertilizers by avoiding substrate acidification.

• Wastewater treatment: H₂S odor control in municipal and industrial sludge lines. Calcium Nitrate promotes biological oxidation of sulfides, eliminating toxic H₂S emissions more effectively than iron salts and without pH crashes.

• Concrete & construction: Chloride-free accelerator for shotcrete and cold-weather pouring. Reduces setting time by 30–50% versus traditional calcium chloride while preserving rebar integrity – critical for tunnels, bridges, and pre-stressed concrete.

• Latex & explosives manufacturing: Coagulant for synthetic latex and oxidizing agent in blasting agents. Provides consistent particle dispersion and energetic performance superior to sodium-based alternatives.

4. Competitive Advantages

• Quality consistency: ISO 9001:2025 certified production with SGS/Intertek batch testing; impurity limits (Na, Cl, heavy metals) guaranteed ≤0.05% each.

• Supply reliability: Multi-sourced raw material contracts and safety stock held across three continental hubs (Asia, Europe, NAFTA) – 99.2% on-time-in-full rate.

• Logistics capability: Dedicated moisture-controlled containers and anti-caking coatings for humid-route shipments.

• Price competitiveness: Direct mill pricing with volume tiering; long-term fixed-rate contracts available for 500+ MT annual off-take.

• Sustainability & compliance: Low-carbon production process (Scope 1&2 emissions ≤0.45 t CO₂e/t product); REACH, RoHS, and EU Fertilizing Product Regulation (2019/1009) compliant.

• Technical support: Full SDS, COA, application whitepapers, and agronomic modeling tool access via buyer portal.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20MT (equivalent to one 20-foot container or 800 x 25 kg bags)

• Loading capacity: 20MT per 20′ dry container (palletized stretch-wrapped); 25MT per 40′ high-cube container for big-bag configuration
