Calcium Nitrate

CAS 13477-34-4 · Formula CaH8N2O10 · MW 236.15 g/mol

A fully water-soluble nitrate salt that delivers plant-available calcium and nitrogen while accelerating concrete set and curbing sewer odor. It is used as a fast-acting calcium-and-nitrogen fertilizer, as a set accelerator for concrete (notably in cold-weather placement), and in wastewater treatment to suppress hydrogen sulfide and odor in anaerobic sewer systems.

Frequently Asked Questions

What is calcium nitrate used for?

Calcium nitrate (CAS 13477-34-4) is a water-soluble inorganic nitrate salt used as a fast-acting calcium-and-nitrogen fertilizer (including fertigation), as a set accelerator for concrete — notably in cold-weather placement — and in wastewater treatment to suppress hydrogen sulfide and odor in anaerobic sewer systems.

Is calcium nitrate the same as Epsom salt?

No. Calcium nitrate is the calcium salt of nitric acid, supplying calcium and nitrate-nitrogen. Epsom salt is magnesium sulfate (MgSO4·7H2O) — a different compound supplying magnesium and sulfate. They are not interchangeable.

What is the calcium nitrate formula?

Calcium nitrate is Ca(NO3)2; the tetrahydrate commonly traded carries water of crystallization (listed here as CaH8N2O10, i.e. Ca(NO3)2·4H2O). It is a water-soluble inorganic nitrate salt.

Does RawSource supply calcium nitrate in bulk?

Yes. RawSource distributes calcium nitrate in bulk bags and supersacks to fertilizer, construction-admixture, and wastewater-treatment customers. Send your target volume for a quote on pack sizes and lead time.

What is the cost of bulk calcium nitrate?

Price depends on grade, volume, packaging, and freight, so RawSource quotes per order rather than listing a fixed price. Request a current bulk quote against CAS 13477-34-4.
