Bismuth(III) oxychloride, Powder, 99.9%, -100 mesh

Bismuth oxychloride is utilized in optical coatings due to its high refractive index and pearlescent properties, often used to create interference effects and luster in thin-film applications.

Used as a precursor material for the fabrication of bismuth-based thin films via sputtering processes in the development of photocatalytic and electronic components.

Employed as a source material in vacuum evaporation processes to deposit thin layers for specialized optical and decorative coatings.
