12640-40-3 Usage
General Description
Bismuth oxide, also known as bismuth(III) oxide, is a white solid compound composed of bismuth and oxygen. It is used in a variety of applications, including as a pigment in cosmetics and paint, as a component in glass and ceramic production, and as a catalyst in certain chemical reactions. With its high refractive index and low dispersion, bismuth oxide is also used in the manufacturing of optical glasses and lenses. Additionally, it has potential applications in the fields of electronics and optoelectronics due to its unique electronic properties. Bismuth oxide is considered to be relatively non-toxic compared to other bismuth compounds, making it suitable for a wide range of industrial and commercial uses.
Check Digit Verification of cas no
The CAS Registry Mumber 12640-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,6,4 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 12640-40:
(7*1)+(6*2)+(5*6)+(4*4)+(3*0)+(2*4)+(1*0)=73
73 % 10 = 3
So 12640-40-3 is a valid CAS Registry Number.

The chemostimulation efficiency of the activators Sb2O 3 and Bi2O3 in compositions with a diluent (Al2O3) is a linear function of activator percentage over a wide range of temperatures. This function is not, however, additive to the thicknesses achieved in the presence of individual components. The percentage of the activator elements in the resulting oxide layers coincides with that in the initial compositions in the linear region and differs from it in the nonadditivity region. Thermal analysis in combination with X-ray powder diffraction showed that Al2O3 alters the temperature range and character of the intrinsic transformations of activator oxides.
