Thulium Acetate Tetrahydrate is a moderately water soluble crystalline Thulium source that decomposes to Thulium oxide on heating. It is generally immediately available in most volumes.
Molar mass：364.08 g/mol (anhydrous basis)
Solubility：Moderately soluble in water, strong mineral acids.
Thulium Acetate is the important dopant for silica-based fiber amplifiers. It can also be used in portable X-ray devices that has been bombarded in a nuclear reactor as a radiation source. Used as laboratory reagent, optical glasses, structural ceramics, catalysts, electrical components and photo-optical material. The other main application is used for optical fiber.
