Yttrium Fluoride YF3 CAS 13709-49-4 For Laser Crystal Material

Yttrium fluoride is an important rare earth compound that appears as a grayish white powder or crystal at room temperature. It has a variety of excellent performance and application areas.
In the field of optics, yttrium fluoride is widely used to prepare optical anti-reflection films to improve the performance of optical components because of its low refractive index and wide transmittance band. At the same time, it can also be used as a doping material of optical fiber glass to improve optical fiber communication performance. In addition, yttrium fluoride is also a key raw material for the preparation of rare earth crystal laser materials, such as upconversion luminous materials, expanding the application range of laser technology.
In the field of materials science, yttrium fluoride is an important raw material for the preparation of high-performance phosphors and ceramics. In terms of phosphors, the application of yttrium fluoride improves the performance and stability of phosphors, and extends the service life of lighting and display products. In ceramics, the addition of yttrium fluoride enhances the high temperature resistance and corrosion resistance of ceramic materials, making it widely used in electronics, aerospace and other fields.

products features

Name: Yttrium fluoride, Yttrium fluoride anhydrous

Molecular formula: YF3

CAS: 13709-49-4

Molecular weight: 145.9

Description

Yttrium fluoride is a white powder, insoluble in water, insoluble in hydrochloric acid, nitric acid and sulfuric acid, but soluble in perchloric acid. It is relatively stable in the air and forms insoluble complex salt with ammonium fluoride. The chemical preparation method is to dissolve yttrium oxide in hydrochloric acid, heat the solution to 70-80℃, and then precipitate with 48% hydrofluoric acid. The precipitate is washed, filtered, dried, crushed and dehydrated in vacuum to produce yttrium fluoride.
