Ytterbium Phosphate, Powder, 99.9%, -1250 mesh (3.8 mic aps) approx

Used as a host lattice for rare-earth doping in phosphors and laser materials due to its high chemical and thermal stability.

Fabricated into high-purity targets for the deposition of thin films used in optical and protective coatings.

Applied as a thin film material for optical components requiring specific refractive indices and high transparency in the infrared spectrum.

Utilized as a component in environmental barrier coatings (EBCs) to protect ceramic matrix composites from high-temperature water vapor corrosion.
