Description
Bismuth germanium oxide, also known as bismuth germanate, is a cubic crystal with the formula Bi4Ge3O12 and a less common composition of Bi12GeO20. It has the "evlitine" structure and consists of three GeO3 tetrahedra arranged in a building block, which are then arranged in a cubic close-packed structure. Bismuth germanate is known for its high "electrooptic coefficient" (3.3 pm/V for Bi12GeO20) and is available in the form of white chips or powder with a purity of 99.99995%.

Check Digit Verification of cas no
The CAS Registry Mumber 12233-56-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,3 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 12233-56:
(7*1)+(6*2)+(5*2)+(4*3)+(3*3)+(2*5)+(1*6)=66
66 % 10 = 6
So 12233-56-6 is a valid CAS Registry Number.

Structural and electrical transport studies of reduced in hydrogen surface of bismuth germanate glass
Kusz
, p. 623 - 627 (2003)
Bismuth nanoclusters embedded in germanate glass matrices and surface layer of bismuth grains have been obtained by thermal treatment in hydrogen atmosphere of Bi0.33Ge0.67O1.83 glass. Confirmed by AFM and XRD measurements a simple model of two conducting layers is proposed. The influence of time and temperature of reduction on the properties of the reduced samples have been studied. A change in surface conductivity caused by melting of Bi granules has been observed in all studied samples. The possibility of existence of a superconducting state in reduced bismuth germanate glasses has been discussed.
