GADOLINIUM FLUORIDE Chemical Properties,Usage,Production

Uses

Gadolinium Fluoride is used for making optical glass and dopant for Gadolinium Yttrium Garnets which have microwave applications. Gadolinium is used for making Gadolinium Yttrium Garnet, it has microwave applications and is used in fabrication of various optical components and as substrate material for magneto-optical films.

Chemical Properties

White powder. Gadolinium fluoride, on heating or on contact with acids/acid fumes, decomposes and emits toxic fumes of fluorine, hydrogen fluoride vapours, and oxides of gadolinium.

Uses

Employed in the synthesis of non-oxide glasses.1,2

Uses

Gadolinium(III) fluoride, anhydrous is employed in the synthesis of non-oxide glasses.
