Description
Bismuth(III) sulfide, also known as bismuthinite or bismuth glance, is a brownish-black orthogonal crystal with a density of 6.78 g/cm3 and a hardness of 2 Mohs. It melts at 850°C and is insoluble in water but soluble in acids. Bismuth(III) sulfide can be precipitated by hydrogen sulfide from bismuth solutions and occurs naturally as the mineral bismuthinite.
Uses
Used in Chemical Industry:
Bismuth(III) sulfide is used as a starting material to produce various other bismuth compounds, which have applications in different industries.
Used in Glass Industry:
Bismuth(III) sulfide is used as a colorant in the glass industry, providing a unique color to the final product.
Used in Electronic Ceramics:
Bismuth(III) sulfide is utilized in the production of electronic ceramics, which are essential components in various electronic devices.
Used in Scintillator BGO:
Bismuth(III) sulfide is employed in the manufacturing of scintillator BGO (bismuth germanate oxide), which is a crucial material in the detection of gamma rays.
Used in Superconductors:
Bismuth(III) sulfide is also used in the development of superconductors, materials that exhibit zero electrical resistance and expulsion of magnetic fields when cooled below a certain temperature.
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
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 1345-07-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,4 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1345-07:
(6*1)+(5*3)+(4*4)+(3*5)+(2*0)+(1*7)=59
59 % 10 = 9
So 1345-07-9 is a valid CAS Registry Number.
