Thallium Oxide Industrial Grade 99.9%

Thallium oxide include two kinds of oxides, thallium(I) oxide and thallium(III) oxide. Tl2O is  black powder, however Tl2O3 is brown or dark red powder. Thallous oxide is soluble in water, acid and alcohol. But thallium trioxide is not soluble in water and alkali.  Thallium trioxide dissolve in HCl and release chlorine, however release oxygen when dissolve in sulfuric acid.

Applications

Erbium trifluoridie uses in optical coating, optical fiber dopant, laser crystal, monocrystal raw material, laser amplifer, catalytic addictives and so on.

Erbium(III) fluoride film play important roles in space optics, photo-communication, spectrograph and other large optical systems. In far infrared region, rare earth fluorides as YF3LaF3CeF3, HfF4, NdF3 were reported with their optical constant, but rare for ErF3. ErF3 is heavy rare earth fluoride that belong to lanthanum series. In files of recent ten years, reports about erbium(III) fluoride’s infrared ray optical constant is few. Most of researches focus on infrared transmittance glass containing ErF3.
