• Uses: Thulium(III) acetate hydrate is a moderately water soluble crystalline Thulium source that decomposes to Thulium Oxide on heating. It is generally immediately available in most volumes. It can also be used in portable X-ray devices that has been bombarded in a nuclear reactor as a radiation source. The other main application is used for optical fiber. Dysprosium(III) fluoride is specialized uses in laser glass, phosphors, Dysprosium halide lamp and also as the main raw materials for making Dysprosium metal.

Technology Process of Dysprosium trifluoride

There total 30 articles about Dysprosium trifluoride which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

NH4(1+)*F(1-)*2DyF3=NH4Dy2F7 → dysprosium(III) fluoride (13569-80-7) + hydrogen fluoride (7664-39-3,12381-92-9,32057-09-3,74835-82-8) + ammonia (7664-41-7)

Guidance literature:

In neat (no solvent); decompn.; determination of equilibrium constant, decompn.-pressure, free enthalpy and react.-enthalpy for different temp.;;

Reference yield:

dysprosium((III) oxide + hydrogen fluoride (7664-39-3,12381-92-9,32057-09-3,74835-82-8) → dysprosium(III) fluoride (13569-80-7)

Guidance literature:

In hydrogenchloride; nitric acid; Dy2O3 was dissolved in HCl-HNO3, pptd. with HF, dehydrated under streamof HF-N2 at temp. gradually raised to about 1000 K;
