Ytterbium(III) fluoride (YbF3) is an inorganic chemical compound. Ytterbium fluoride, produces low-index film layers with extremely durable mechanical properties that exhibit good transparency in the UV through infrared (14 µm ) regions. The films are insoluble and show low stress, making compounds of Ytterbium Fluoride suitable for AR coatings in the 8 to 14 µm region, including high power CO2 laser coatings.
YbF3 and BaSO4 nanoparticles were incorporated into the powder component of Riva SC (SDI Ltd., Bayswater, Australia) at 1, 2, 5, 10, 15, and 25% by weight. Capsules were assembled at a powder:liquid ratio of 2.9:1, activated and mixed, and the resultant pastes evaluated for working time, initial setting time, 24-h surface hardness and 24-h compressive strength.
Ytterbium is a chemical element with the symbol Yb and atomic number 70. It is the fourteenth and penultimate element in the lanthanide series, or last element in the f-block, which is the basis of the relative stability of the +2 oxidation state. However, like the other lanthanides, the most common oxidation state is +3, seen in its oxide, halides and other compounds. In an aqueous solution, like compounds of other late lanthanides, soluble lutetium compounds form a complex with nine water molecules.
