| | BISMUTH SULFIDE Usage And Synthesis |
| Chemical Properties | Blackish brown powder | | Physical properties | Brownish black orthogonal crystal; density 6.78 g/cm3; hardness 2 Mohs; melts at 850°C; insoluble in water; soluble in acids. | | Occurrence | Bismuth sulfide occurs in nature as the mineral bismuthinite (bismuth glance). It is used as a starting material to produce many other bismuth compounds. | | Uses | Bismuth(III) sulfide is used as a starting material to produce other bismuth compounds. It is used in glass industry as a colorant, electronic ceramics, scintillator BGO and in superconductors. | | Preparation | The compound occurs in nature as mineral bismuthinite. It can be prepared in the laboratory by passing hydrogen sulfide into a solution of bismuth chloride or any soluble bismuth salt:
2BiCl3 + 3H2S → Bi2S3 + 6HCl
Alternatively, bismuth sulfide may be obtained by melting a mixture of bismuth and sulfur.
2Bi + 3S → Bi2S3 | | General Description | Bismuth(III) sulphide can be precipitated by hydrogen sulphide from bismuth solutions. 1 | | Flammability and Explosibility | Non flammable |
