Bismuth sulfide desociation
WebBismuth chalcogenides are a family of semiconductors composed of Bi and group VI elements, including bismuth oxide (Bi2 O 3 ), bismuth sulfide (Bi 2 S 3), bismuth selenide (Bi2 Se 3 ), and bismuth telluride (Bi 2 Te 3 ). WebJan 1, 2024 · This method of producing bismuth sulfide simply involves the precipitation of the compound in a controlled manner from a homogeneous solution. It is achieved by using the precursors of bismuth and sulfur ions with appropriate stability constant. The reaction between the two ions is as shown in equation 1. 2Bi3+ (aq) + 3S2− (aq) → Bi2S3 (s) (1)
