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 [1]. It is used in the production of malleable iron and as a catalyst in the manufacture of acrylic fibers [2]. Additionally, bismuth promotes noble metal-based catalysts for the selective oxidation of alcohols, aldehydes and carbohydrates with molecular oxygen in liquid phases.[3]

Application

Bismuth granules are used in the preparation of bismuth nanoparticles by solution dispersion method.[4][5] It is a precursor to synthesize bismuth-silicate glasses.[6]

Bismuth is used as a precursor in the synthesis of Cu₃BiS₃ based solar device.[7]
