,%20partnering%20with%20Kaifeng%20Darui.jpg)
Bismuth Subcarbonate, also known as Bismuth Carbonate Basic or Bismuth Oxycarbonate, is an inorganic compound with the chemical formula (BiO)₂CO₃ or Bi₂O₂(CO₃). It appears as a fine, white or pale yellow powder that is odorless and tasteless. The compound is insoluble in water and alcohol but dissolves readily in mineral acids such as nitric acid and hydrochloric acid, as well as concentrated acetic acid. Its relative density is approximately 6.86 g/cm³, and it decomposes into carbon dioxide and bismuth oxide at around 308°C.
With a molecular weight of 509.97 g/mol, Bismuth Subcarbonate is stable in air but may gradually turn brown when exposed to light. Its unique chemical properties, including its antacid and mild antiseptic characteristics, make it a critical ingredient in various applications, particularly in the pharmaceutical industry.

Applications of Bismuth Subcarbonate
Bismuth Subcarbonate’s versatility stems from its unique chemical and physical properties, enabling its use across multiple industries. Below are some of its primary applications:
1. Pharmaceutical Industry
Bismuth Subcarbonate is widely used in the pharmaceutical sector due to its antacid, astringent, and mild antiseptic properties. It serves as an active ingredient in medications designed to treat gastrointestinal disorders such as indigestion, diarrhea, gastric ulcers, and duodenal ulcers. By forming a protective coating over mucosal wounds, it shields the stomach lining from irritation caused by gastric acid, promoting healing and alleviating discomfort.
Historically, Bismuth Subcarbonate was used as an X-ray contrast medium due to its opacity, although it has largely been replaced by barium sulfate for this purpose. It is also employed in topical protectants for external ulcers, fistulas, and inflamed mucous membranes. The compound’s ability to treat conditions like bacterial dysentery, acute mucosal gastritis, and enteritis further underscores its importance in medical applications.
2. Cosmetic Industry
In cosmetics, Bismuth Subcarbonate is valued for its soothing and anti-inflammatory properties. It is incorporated into formulations for skin care products, particularly those targeting sensitive or irritated skin. Its pearlescent quality also makes it a popular additive in pearlescent plastics and cosmetic coatings, enhancing the aesthetic appeal of products. The growing demand for natural and gentle ingredients in personal care products has further boosted its use in this sector.
3. Industrial and Other Applications
Beyond pharmaceuticals and cosmetics, Bismuth Subcarbonate finds applications in various industrial processes. It is used as a precursor for synthesizing other bismuth compounds, such as bismuth oxide, through calcination. In ceramics, it serves as a component in enamel fluxes and glazes, imparting a glossy finish. Additionally, it is employed in the production of radiopaque catheters and as an additive in fireworks to create effects like “Dragon’s eggs.” Its antibacterial properties have also led to its use in nanotube arrays for biomedical applications.
In agriculture, Bismuth Subcarbonate has been combined with pesticides to enhance insect feeding on treated foliage, although this application is less common today.
