English name: Yttrium Fluoride
CAS NO.13709-49-4
Molecular formula: YF3
Molecular weight: 145.901109
Insoluble in water, insoluble in hydrochloric acid, nitric acid and sulfuric acid, but soluble in perchloric acid.
It is hygroscopic and stable in the air.
With the development of infrared materials and infrared technology in new research and application fields, it is urgent.
It is necessary to have a stable and high-quality film in infrared band. YF3 material is characterized by its excellent properties.
It has excellent optical properties and is widely used in infrared band, especially in wide band gap.
It has high transmittance in a wide band from ultraviolet to infrared, so yttrium fluoride material is the first.
The first choice of low refractive index materials in interference filters and infrared optical coating components.
