Understanding the molecular significance, manufacturing methodologies, and emerging global market trends of Ca(NO3)2·4H2O.
Calcium Nitrate Tetrahydrate, chemically formulated as Ca(NO3)2·4H2O (often represented as Ca No3 24h2o in search indexing), is a highly soluble crystalline compound essential to multiple industrial, agricultural, and infrastructural sectors. In its pure crystalline state, it represents a core precursor for specialized chemical syntheses, offering high solubility in water and alcohol. Historically utilized primarily as a quick-release fertilizer to counter calcium deficiency in crops, the chemical has seen a rapid technological transition toward advanced industrial application vectors, including sewage treatment, concrete accelerator additives, and molten salt thermal energy storage formulations.
The current global market for Ca(NO3)2·4H2O is experiencing structural shifts driven by environmental mandates and advanced engineering frameworks. As governments impose stricter discharge limits on wastewater treatment facilities, industrial-grade Calcium Nitrate Tetrahydrate has emerged as a premier agent for biochemical odor control and anoxic denitrification. Furthermore, the global concrete industry is rapidly adopting it as a non-chloride setting accelerator to ensure construction integrity under sub-zero temperatures.
Procurement teams face critical variables when selecting a manufacturing partner for Ca No3 24h2o. These include moisture content control, crystalline grain size uniformity, anti-caking profile, and trace metal limits. The table below represents the benchmark differences required for various application grades:

In-depth responses resolving technical, logical, and logistical queries regarding Calcium Nitrate Tetrahydrate.
Calcium Nitrate Tetrahydrate [$Ca(NO_3)_2 \cdot 4H_2O$] contains four molecules of crystallized water bound within its chemical lattice, resulting in a molecular weight of approximately 236.15 g/mol. Anhydrous calcium nitrate [$Ca(NO_3)_2$] is void of crystal water. The tetrahydrate form is preferred in agricultural solutions and coagulation processes due to its lower dissolution heat requirement and high solubility, though it requires specialized storage to avoid deliquescence under high humidity conditions.
Due to its hygroscopic nature, Calcium Nitrate Tetrahydrate is prone to caking. We resolve this challenge using two primary methodologies: first, by leveraging high-tech continuous crystallization to output highly uniform, round-shaped crystals that minimize interfacial contact; second, by utilizing moisture-proof packaging comprising heavy-duty PE inner liners sealed within high-density PP woven bags. Custom food-grade or inorganic anti-caking coatings can also be introduced at client requests.
Yes, under standard IMDG regulations, Calcium Nitrate Tetrahydrate is classified as a Division 5.1 Oxidizer (UN Number 1454) due to its chemical oxygen content. This status mandates strict compliance with chemical hazard packaging, container segregation, and declaration requirements. Vojin possesses extensive experience with UN-certified packaging regulations, ensuring smooth custom transits.
In municipal sewage and wastewater systems, H2S gas generated by sulfate-reducing bacteria causes pipe corrosion and noxious odor issues. Introducing Calcium Nitrate Tetrahydrate provides a nitrate source that allows denitrifiers to metabolize organically, bypassing sulfate reduction. This effectively prevents the formation of hydrogen sulfide while accelerating the purification process via denitrification.
Our manufacturing plant can adjust the pH scale of solutions, customize crystalline granular sizing, modify caking inhibitor ratios, and control trace heavy metal limits to meet specific electronic or industrial guidelines. Packaging options include 25kg, 50kg, and 1,000kg jumbo bulk bags with custom branding.
