PbBiS
PbBiS refers to a chemical compound or a system involving lead (Pb), bismuth (Bi), and sulfur (S). The specific stoichiometry and arrangement of these elements determine the exact compound and its properties. One notable compound within this system is bismuthinite, which has the chemical formula Bi2S3 and can incorporate lead, forming solid solutions. Lead and bismuth are both heavy metals with metallic properties, while sulfur is a nonmetal. When combined, they can form various sulfide minerals and synthetic materials.
The Pb-Bi-S system is of interest in mineralogy due to the natural occurrence of lead-bearing bismuth sulfides
