High Purity Calcium Nitrate Tetrahydrate Crystalline Fertilizer & Industrial Grade
Product Name: High Purity Calcium Nitrate Tetrahydrate Crystalline Fertilizer & Industrial Grade
Molecular formula: Ca(NO3)2.4H2O
Molecular weight: 236.15
Product Brief / Short Description
This product is high-purity Calcium Nitrate Tetrahydrate crystals, providing a highly soluble source of calcium ions (Ca²⁺) and nitrate ions (NO₃⁻). As a superior dual-nutrient compound, it is extensively used as a premium calcium fertilizer in agriculture. In industrial fields, it serves as an efficient concrete accelerator, a component in cold storage mixtures, and a chemical intermediate. It features high purity, excellent water solubility, and ease of handling.

Main Applications
Agriculture (Primary Use):
Premium Calcium Fertilizer: Rapidly corrects calcium deficiency disorders in crops (e.g., blossom-end rot in tomatoes/peppers, bitter pit in apples, tip burn in lettuce).
Fertigation & Foliar Feeding: Ideal for fertigation systems (drip/ sprinkler irrigation) and as a foliar spray during critical growth stages.
Hydroponics Nutrient Solution: A standard calcium and nitrogen source for Hoagland and other hydroponic formulations.
Target Crops: Fruits (apples, citrus, berries), vegetables (tomatoes, peppers, leafy greens), greenhouse crops, and cash crops.
Industrial Uses:
Concrete Additive: Acts as a non-chloride, corrosion-inhibiting accelerator for setting and hardening concrete, especially in cold weather.
Refrigeration Brine: A key component in low-temperature freezing mixtures.
Chemical Intermediate: Used in the production of other calcium salts, latex coagulants, and wastewater treatment chemicals.
Rubber Industry: Serves as a coagulating agent in the manufacture of synthetic rubber.
Precautions for safe handling
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
