Description
Ytterbium oxide is the oxide product of the rare earth metal element ytterbium. It can be used in thermal shielding coating materials, electronic materials, active device materials, battery materials and bio-pharmaceuticals. It is also applied to fiber amplifier and fiber optic technologies and in lasing applications. The spectral emissivity of ytterbium oxide-based materials also makes it be used as selective emitter in thermophotovoltaic devices.

Chemical Properties
Ytterbium (III) oxide is white powder and pieces, has no odour, is insoluble in water, and is incompatible with strong acids, oxidising agents, and carbon dioxide.
Physical properties
Colorless cubic crystals when pure; tinted brown or yellowish white in presence of thulia; density 9.17 g/cm3; insoluble in water; soluble in hot dilute acids.
Uses
Different sources of media describe the Uses of 1314-37-0 differently. You can refer to the following data:
1. Ytterbium oxide (Yb2O3) is used to make special alloys, ceramics, and glass. It can be used
for carbon arc-lamp electrodes that produce a very bright light.
2. Ytterbium(III) oxide is being applied to numerous fiber amplifier and fiber optic technologies. High purity Ytterbium Oxide are widely applied as a doping agent for garnet crystals in lasers a important colorant in glasses and porcelain enamel glazes.. As Ytterbium Oxide has a significantly higher emissivity in the infrared range a higher radiant intensity is obtained with Ytterbium-based payloads.
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.
