Bismuth lumps are high-purity materials used in various industrial applications, including pharmaceuticals, cosmetics, and low-melting point alloys. They are known for their excellent non-toxicity, high melting point, and unique properties.
Product Overview
Bismuth lump is a metal element with a red-white luster, symbolized as Bi with an atomic number of 83. Bismuth has a density of 9.8 g/cm³, a melting point of 271.3°C, and a boiling point of 1560°C. It is brittle, with poor electrical and thermal conductivity. As a strongly diamagnetic metal, bismuth's resistivity increases and its thermal conductivity decreases in a magnetic field. Bismuth lump is widely used in various fields, especially in environments requiring low melting points, chemical stability, and magnetic materials, showcasing its unique advantages.
