Terbium Oxide Powder Introduction

Terbium (III, IV) oxide (also known as tetraterbium heptaoxide) is relatively stable and more comfortable to be stored. It is used as a redox catalyst in reactions involving oxygen. At high temperatures, it can liberate oxygen. It finds applications in the manufacture of glass, optic, and ceramic. Nanoparticles of terbium oxide are used as analytical reagents for the determination of drugs in food. Tb4O7 is one of the main commercial terbium compounds. Terbium Oxide has an essential role as an activator for green phosphors used in color TV tubes. Meanwhile, Terbium Oxide is also used in special lasers and as a dopant in solid-state devices. It is also frequently used as a dopant for crystalline solid-state devices and fuel cell materials. Terbium Oxide is one of the chief commercial Terbium compounds. Produced by heating the metal oxalate, Terbium Oxide is then used to prepare other Terbium compounds.
