Gadolinium Oxide, also called Gadolinia, is used for making optical glass and gadolinium yttrium garnets which have microwave applications. High purity of Gadolinium Oxide is used for making phosphors for colour TV tube. cerium oxide (in the form of gadolinium doped ceria) creates an electrolyte with both high ionic conductivity and low operating temperatures that are optimal for cost-effective production of fuel cells. And the other application is used for neutron absorption.
