Highlights at a glance

Calcium formate (Ca(HCOO)₂), with a molecular weight of 130.12 g/mol, is a white, free-flowing crystalline powder characterized by its orthorhombic, needle-like crystal structure. It exhibits good solubility in water—16.6 g/100g at 20°C, increasing to 24.1 g/100g at 50°C—and forms a slightly alkaline solution (pH 6.5–8.0 at 10% concentration). The compound has a bulk density of 0.7–0.9 g/cm³ and low moisture content, ≤0.5% for industrial grade and ≤0.2% for feed and food grades. It is thermally stable up to 200°C, decomposing above this temperature without a distinct melting point. Moderately hygroscopic, calcium formate is easier to handle than highly hygroscopic alternatives. These properties make it suitable for use in animal feed, construction materials, and industrial applications where stability and solubility are essential.
