Chemical formula: TbI₃.
Molecular weight: 539.638 g/mol.
Appearance: Usually colourless flaky crystals, but easily deliquesced to white in humid air.
Density: about 5.200 g/cm³.
Melting point: 946 °C.
Boiling point: >1300 °C.
Stability: TbI₃ powder is stable at room temperature and pressure, but may decompose or deteriorate by chemical reaction when heated, exposed to light or in contact with certain substances.
Oxidising and reducing properties: Terbium iodide is oxidising at the +3 valence and can be reduced to a lower valence state in some chemical reactions.
Optics: Terbium iodide powder has certain applications in optical materials, and can be used to prepare optical glass, crystals, etc. to improve the optical properties of the material, such as refractive index, transmittance and so on.
Electronic Devices: TbI₃ is used as a dopant in semiconductor materials to regulate the electrical properties of electronic devices, such as transistors and integrated circuits.
Chemical analysis: Terbium Iodide can be used as an analytical reagent in analytical chemistry to detect and analyse the composition and content of certain 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.
