Explore our foundational range of highly pure, rapid-dissolving chemical compounds engineered to meet strict international specifications.
Calcium Nitrate Soluble, widely identified by its molecular configuration representing a double salt formula of 5Ca(NO3)2·NH4NO3·10H2O or anhydrous equivalent Ca(NO3)2, stands as a critical compound across global industries. Its exceptional solubility, reaching upwards of 1200 g/L at 20°C, establishes it as the premier choice for applications where sediment-free solutions are vital.
Unlike standard industrial grade fertilizers that possess lower purity thresholds, high-end water-soluble calcium nitrate is processed to minimize insoluble matter (typically < 0.1%). This prevents nozzle clogging in micro-drip fertigation systems and ensures clean reactions when used in municipal concrete setting accelerators or water clarification networks.
Our proprietary refining procedures involve double recrystallization stages which systematically extract heavy metals, sodium chloride traces, and iron compounds. This yields an exceptionally white, dust-free spherical prill with uniform granulometry (1-4mm range), maximizing flowability and avoiding compaction during ocean transport.
Discover how regional environmental, industrial, and infrastructure frameworks dictate the localized usage parameters of soluble calcium nitrate.
In water-scarce agricultural corridors (such as the MENA region and Southern Europe), calcium nitrate acts as the bedrock for drip-fed mineral nutrition, neutralising soil salinity and maintaining crop vigor in saline soils.
In high-latitude infrastructure projects (Nordic regions, Canada, and Northern USA), soluble calcium nitrate is utilized to accelerate hydration kinetics, allowing concrete pouring even in sub-freezing temperatures without structural cracking.
Metropolitan sewerage operators leverage the nitrate ion's oxidizing potential to selectively halt septic conditions, effectively eliminating foul odors and corrosive hydrogen sulfide gas emissions in municipal wastewater lines.
Leveraging continuous technology optimizations to deliver unparalleled output stability, precision grading, and green manufacturing practices.
As standard-setting manufacturers, our production employs a high-efficiency synthetic reaction involving premium grade nitric acid (HNO3) and high-calcite calcium carbonate (CaCO3). The reaction proceeds under strict temperature and pH controls to maximize product stability and prevent organic carbon contamination.
| Analytical Parameter | Agricultural Drip-Grade Spec | Industrial/Thermal Grade Spec |
|---|---|---|
| Calcium Content (Ca) | ≥ 19.0% | ≥ 23.5% (as CaO equivalent) |
| Total Nitrogen (N) | ≥ 15.5% | ≥ 11.7% (Ammonium-free options available) |
| Water Insoluble Matter | ≤ 0.1% | ≤ 0.05% |
| pH Value (10% Solution) | 5.0 - 7.0 | 5.5 - 7.5 |
| Heavy Metals (as Pb) | ≤ 10 ppm | ≤ 5 ppm |
By implementing a custom multi-stage crystallisation loop, we successfully mitigate ammonium levels when manufacturing pure industrial-grade calcium nitrate. This is essential for applications such as concrete formulation or latex coagulation baths where the presence of ammonium ions can trigger undesirable secondary reactions.
Our strategic placement within Shanxi province grants direct integration into key raw material corridors.
