Gadolinium is used in alloys of iron and chromium to improve resistance to high temperatures and oxidation. Gadolinium is used to make gadolinium yttrium garnets which have microwave applications. Gadolinium compounds are used as green phosphors in color television picture tubes.Because of its magnetic properties, gadolinium is also used in intravenous radiocontrast agents in magnetic resonance imaging (MRI).aturally occurring gadolinium is a mixture of seven isotopes and they are found in the percentages shown: 152 Gd (0.2%), 154 Gd (2.2%), 155 Gd (14.8%), 156 Gd (20.5%), 157 Gd (15.7%), 158 Gd (24.8%) and 160 Gd (21.9%). The most abundant isotope is 158 Gd at 24.8%.
