Barium carbonate is a white insoluble salt which finds its largest use in the ceramics industry in the production of ceramic products.

2025年2月17日 · Barium carbonate is used in oil well drilling to insolubilize gypsum and inhibit coagulation; in ferrous metallurgy for steel carburizing; in chloralkali cells for treating salt brines to remove sulfates; and to make ferrites, and barium titanate.

2024年7月11日 · Barium carbonate is a fascinating chemical compound with a wide range of applications and properties. Chemically, it is denoted as BaCO3 and is a salt formed from the reaction between barium ions (Ba²⁺) and carbonate ions (CO₃²⁻).

2024年6月29日 · Barium carbonate is the inorganic compound with the formula BaCO 3. It is a salt composed of barium cations (Ba²⁺) and carbonate anions (CO₃²⁻). Like most alkaline earth metal carbonates, it is a white salt that is poorly soluble in water. It …

2023年11月18日 · Barium carbonate is an insoluble barium salt of carbonic acid with the formula BaCO3, even less soluble than barium sulfate. Unlike BaSO 4, barium carbonate reacts with acids and can serve as precursor to any barium salt. Heat causes it to decompose, liberating carbon dioxide and turning into the oxide BaO.

It is a white salt that, like most other alkaline earth metal carbonates, is weak bases in water solution but soluble in most acids (except sulphuric acid). To put it another way, it is one of the most economically or commercially significant barium compounds.
