Silvery Red Metal Bismuth Bi High Purity Semiconductor Material

Bismuth (Bi): High-Purity Semiconductor Material, Low-Melting Alloys, and Radiation Shielding

Molecular formula: Bi. Appearance: light gray, brittle and hard texture, orthorhombic coarse-grained crystal. Melting point: 271.3℃. Boiling point: (1560±5)℃. Relative density: 9.80 g/cm³. Soluble in hot sulfuric acid, nitric acid, aqua regia; slowly soluble in hot hydrochloric acid; insoluble in water. Stable at room temperature. Burns with pale blue flame when heated, producing yellow or brown bismuth oxide. Molten metal expands after solidification.

About Bismuth
Bismuth powder can spontaneously ignite in chlorine gas. When heated, it directly combines with bromine, iodine, sulfur and selenium to form trivalent compounds. Insoluble in dilute hydrochloric acid and dilute sulfuric acid; soluble in nitric acid and concentrated sulfuric acid to form trivalent bismuth salts. Discovered in 1753 by Englishman Geoffroy the Younger. Exists in nature in both free and combined states. Main minerals include bismuthinite and bismite. Abundance in Earth's crust: 2.0×10-5%. Mainly used for producing low melting point alloys (melting point between 45℃ and 100℃), applied in automatic fire extinguishing devices, fuses and solders in fire protection and electrical industries. Also used for type metal alloys, pharmaceuticals, etc. Produced by roasting bismuthinite to obtain bismuth trioxide, then reduced with carbon to get bismuth.
