Description and 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.
