[5] Calcium formate is stable at room temperature,[5] is flammable and forms orthorhombic crystals.

15 g/kg is the maximum recommended feed concentration within EU – this level is thought to be safe for pigs, chickens, fish and ruminants.

Calcium formate in tannage formulation promotes faster, more efficient leather penetration of the chrome.

[4] As a grout and cement additive, calcium formate imparts a number of desirable properties in the final product, e.g. increased hardness and decreased setting time.

Its addition is desirable for work at low temperature and for inhibition of corrosion of metal substrates within cement/grout.

[8] Calcium formate could be used to remove environmentally harmful (see acid rain) sulfur oxides (SOX) from fossil fuel exhausts of e.g. power plants.

Calcium formate is separated from the solution, heat treated to remove formaldehyde and then dried.

Ingesting liquids with high calcium formate concentrations cause severe gastrointestinal lesions.
