Gadolinium Oxalate 99.999% is used for making optical glass and dopant for Gadolinium Yttrium Garnets which have microwave applications. High purity of Gadolinium Oxalate is used for making phosphors for colour TV tube. When mixed with EDTA dopants, it is used as an injectable contrast agent for patients undergoing magnetic resonance imaging. With its high magnetic moment, Gadolinium can reduce relaxation times and thereby enhance signal intensity. And it is the important application in neutron absorption.
