Description
Niobium oxide, also known as niobium pentoxide (Nb2O5), is a white crystalline powder with a density of 4.60 g/cm3. It melts at 1,512°C and is insoluble in water, but soluble in hydrofluoric acid. Niobium pentoxide is used in various industries due to its unique properties, such as increasing the refractive index of optical glasses and enhancing the capacity of multi-layered ceramic capacitors.
Uses

Preparation
Niobium pentoxide is produced as an intermediate during recovery of Nb metal from ores (See niobium). Also, the pentoxide may be produced by igniting niobium metal powder, niobium carbide, or niobium fluoride in oxygen.
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 1313-96-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,1 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1313-96:
(6*1)+(5*3)+(4*1)+(3*3)+(2*9)+(1*6)=58
58 % 10 = 8
So 1313-96-8 is a valid CAS Registry Number.
