Description

Bismuth CAS NO 7440-69-9 is a brittle, crystalline, post-transition metal with a distinctive pinkish-white hue and low thermal conductivity. It is valued in industrial applications for its low toxicity, high density, and unique physical properties, including a low melting point and expansion upon solidification. This metal is essential for manufacturers in the pharmaceutical, metallurgical, electronics, and chemical catalyst sectors seeking reliable, high-purity material for specialized formulations and alloys.

Application

• Pharmaceuticals: Key ingredient in bismuth subsalicylate, used in gastrointestinal medications for its protective and antimicrobial effects.
• Metallurgy: Used as an alloying element in fusible alloys (e.g., Wood's metal) for fire sprinklers, solders, and casting, and as a lead replacement in brass and steel.
• Electronics & Semiconductors: Employed in thermoelectric materials for cooling devices (Peltier coolers) and as a component in low-temperature solders for sensitive electronic components.
• Chemical Catalysis: Serves as a catalyst or catalyst support in various organic synthesis reactions within the chemical manufacturing industry.
• Cosmetics & Pigments: Used to provide pearlescent effects in cosmetics (bismuth oxychloride) and historically in pigments (bismuth vanadate for yellow).
• Nuclear Shielding: Utilized in specific applications for radiation shielding and as a carrier for actinides in nuclear fuel processing.
