calciumbased

Calciumbased is an adjective used to describe substances, materials, or formulations in which calcium or calcium-containing compounds are a primary component. The term encompasses inorganic salts, oxides, and minerals as well as composite materials where calcium plays a central structural or functional role.

Common calcium-based compounds include calcium carbonate (CaCO3), calcium phosphate (a family including hydroxyapatite Ca10(PO4)6(OH)2), calcium sulfate (CaSO4), calcium oxide (CaO), and calcium hydroxide Ca(OH)2. These compounds occur naturally or are produced industrially and can be used individually or as constituents in more complex materials such as cement, plaster, and fillers.

Applications include construction and architecture (lime mortars, Portland cement components), biomedical and dental fields (bone graft substitutes, calcium phosphate cements), nutrition and supplements (calcium carbonate and calcium citrate as dietary sources), agriculture (agricultural lime to neutralize acidic soils and supply calcium to plants), and water treatment or food processing as additives or stabilizers. In research, calcium-based systems are explored for energy storage, such as calcium-ion batteries, and in catalysis.

Environmental and safety considerations vary by compound. Quicklime and slaked lime (CaO and Ca(OH)2) are caustic and require careful handling. Calcium-based products are generally abundant and relatively inexpensive, but extraction and processing have environmental footprints. The term calciumbased thus covers a broad range of materials with calcium at their core.
