Bismuth Metal Pellets
High-Purity Bismuth for Industrial, Research, and Manufacturing Applications
Bismuth (Bi) is a silvery-white crystalline metal with a slight pink tint and atomic number 83. It is one of the few heavy metals recognized for its comparatively low toxicity, making it an attractive alternative to lead in many commercial and industrial applications. Bismuth combines a unique set of physical properties, including high density, low melting point, low thermal conductivity, diamagnetism, and the unusual ability to expand slightly as it solidifies. These characteristics make it valuable in metallurgy, electronics, laboratory research, and specialty manufacturing.
Chemical Store supplies bismuth metal pellets suitable for industrial processing, alloy production, laboratory use, and research and development.
