Terbium is a silvery-white, rare earth metal found in cerite, gadolinite, and monazite. This element was discovered by Swedish chemist Gustav Mosander, who also discovered lanthanum and erbium. Soft enough to be cut with a knife, terbium melts at 1356°C. Until the recent advent of ion exchange techniques, it had never been isolated in pure form. Sodium terbium borate is used as a laser material and emits coherent light at 0.546 μm. In fuel cells, terbium is often combined with zirconium oxide to stabilize crystals at elevated temperatures.
