Terbium oxide powder is an oxide formed by the combination of the rare earth element terbium and oxygen. This seemingly ordinary dark brown powder is actually the “green gem” of the rare earth family, used in the production of metallic terbium, magneto-optical glass, phosphors, magneto-optical storage materials, and chemical additives.
VIMATERIAL offers high-purity terbium oxide powder, which can be customized to your needs. Contact us for a quote.
Chemical formula: Tb4O7
Molecular mass: 747.69g/mol
Appearance: Dark brown
Density: about 7.3g/cm³

Fluorescent material field: Terbium Oxide can be used as an activator of green phosphor for colour TV picture tubes, fluorescent lamps, etc., which can emit green light in the excited state.
Magneto-optical materials: Terbium Oxide used in the manufacture of magneto-optical storage materials, such as magneto-optical discs can be used as computer storage elements, its storage capacity compared to ordinary storage elements have been significantly improved.
Solid-state devices: Terbium is used as a dopant in solid-state devices, such as solid-state lasers, to improve the performance of the devices.
Our terbium oxide powder is produced and tested in strict accordance with a comprehensive quality management system. From raw material selection to finished product delivery, multiple quality control processes are implemented throughout the entire process. Through rigorous testing of key indicators such as particle size distribution, purity, chemical composition, and impurity content, we ensure batch stability, performance consistency, and high reliability of our products, meeting the high standards required by different application fields.
Packaging: Usually packed in sealed, moisture-proof packaging (such as vacuum bags or sealed containers lined with plastic bags).
Storage: Store in a cool, dry, and well-ventilated environment, avoiding moisture, contamination, and contact with acidic or corrosive substances.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
