Gadolinium Chloride Hydrate Introduction

Gadolinium (III) chloride hydrate is a rare earth compound of Gadolinium. It is water-soluble and hygroscopic. Gadolinium is a rare earth element with a high magnetic moment. Due to its magnetic moment, Gadolinium can enhance signal intensity by reducing relaxation times. It is also used for semiconductor fabrication and nuclear reactor shielding. When combined with EDTA ligands, Gadolinium can be used as an injectable contrast agent for MRIs.

Gadolinium Chloride is used for making optical glass and dopant for Gadolinium Yttrium Garnets, which have microwave applications. High purity of Gadolinium Chloride is used for making laser crystal and phosphors for color TV tube. It is used for making Gadolinium Yttrium Garnet (Gd:Y3Al5O12). It has microwave applications and is used to fabricate various optical components and as a substrate material for magneto-optical films. Gadolinium Gallium Garnet (GGG, Gd3Ga5O12) is used for imitation diamonds and computer bubble memory. It can also serve as an electrolyte in Solid Oxide Fuel Cells (SOFCs).
