High Purity 99.99% Terbium Oxide Tb4O7 CAS 12037-01-3 For Activator Of Phosphor

Terbium oxide is a rare earth oxide, usually appearing as a tan or white powder, with a high melting point and good stability. It is insoluble in water, but soluble in inorganic acids. Because of its unique physical and chemical properties, terbium oxide has been widely used in many fields. In terms of fluorescent materials, it is the key component of producing green phosphors with high brightness and high color purity. In the field of magnetic materials, it is used to prepare rare earth permanent magnets and magneto-optical materials; In addition, terbium oxide is also used in the preparation of terbium salt compounds, chemical reagents and ceramic materials. With the development of science and technology, the application prospect of terbium oxide will be more broad.
