Bismuth brand, chemical structure
Technical characteristics
Shiny metal with a pinkish tinge. under normal conditions — brittle fracture has granular structure, but at temperatures above 150 °C, exhibits plastic properties. In comparison with other metals has a low thermal conductivity is 7.87 W/(m·K) (t° 300°K). Is diamagnetic with the magnetic susceptibility -1,34·10-9 at 293°K, making it the most diamagnetic metal.
