Description

General description

Bismuth is a silvery, very brittle metal with a high metallic luster. In the periodic table, it is next to lead. Bismuth has a variety of applications, including medicine, materials synthesis, organic synthesis, and catalysis . It is used in the production of malleable iron and as a catalyst in the manufacture of acrylic fibers . Additionally, bismuth promotes noble metal-based catalysts for the selective oxidation of alcohols, aldehydes and carbohydrates with molecular oxygen in liquid phases.

Application

Bismuth granules are used in the preparation of bismuth nanoparticles by solution dispersion method. It is a precursor to synthesize bismuth-silicate glasses.

Bismuth is used as a precursor in the synthesis of Cu₃BiS₃ based solar device.
