Calcium nitrate

Calcium nitrate (CAS 10124-37-5), also known as Norway saltpeter, is an inorganic salt supplying both calcium and nitrate ions in a single compound. It functions as a fertilizer nutrient source and concrete accelerator.

This versatile chemical also acts as a biocidal agent across multiple industrial sectors. In agriculture, it delivers water-soluble calcium and nitrogen directly to crops through fertigation systems.

The compound supports cell wall development and reduces post-harvest defects in fruits and vegetables. Concrete and construction applications rely on it as a set accelerator in ready-mix formulations.

It is particularly effective in cold-weather pours where faster strength development is critical. Wastewater treatment plants dose it into anaerobic systems to suppress hydrogen sulfide generation.

This process helps control odor in collection networks and functions as a corrosion inhibitor in concrete reinforcement. It reduces chloride-induced rebar degradation in marine and infrastructure projects.

The product is supplied as white granules, prills, or in liquid solution form. Standard agricultural grades meet fertilizer specifications with defined nitrogen and calcium content for global trade.

Technical grades serve construction and water treatment applications where specific purity is required. Bulk quantities are available for industrial procurement, with granular product being the most common form.
