Description
Ytterbium oxide, with the chemical formula Yb2O3, is an oxide product derived from the rare earth metal element ytterbium. It is known for its colorless cubic crystal structure when pure, and it can exhibit a brown or yellowish tint when impurities like thulium are present. Ytterbium oxide has a density of 9.17 g/cm3, is insoluble in water, and is soluble in hot dilute acids. It is characterized by its white powder and pieces, odorless nature, and incompatibility with strong acids, oxidizing agents, and carbon dioxide. Ytterbium oxide is utilized in various applications, including thermal shielding coating materials, electronic materials, active device materials, battery materials, and bio-pharmaceuticals. Additionally, it finds use in fiber amplifier and fiber optic technologies, as well as in lasing applications, due to its high spectral emissivity in the infrared range.

Preparation
Ytterbium oxide is produced as an intermediate in recovering ytterbium from minerals (See Ytterbium). After opening the ore by digestion with concentrated sulfuric acid or caustic soda solution at high temperatures, rare earths are separated by ion exchange, solvent extraction, or fractional precipitation. Ytterbium fraction is treated with oxalic acid or sodium oxalate to precipitate ytterbium oxalate, which is ignited to yield ytterbium oxide.
Flammability and Explosibility
Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 1314-37-0 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 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1314-37:
(6*1)+(5*3)+(4*1)+(3*4)+(2*3)+(1*7)=50
50 % 10 = 0
So 1314-37-0 is a valid CAS Registry Number.
