Terbium oxide (Tb4O7) | CAS No. 12037-01-3

Q: What are the physical and chemical properties of Terbium oxide (CAS: 12037-01-3)?

Terbium oxide (CAS: 12037-01-3) is a white to yellowish powder with a rhombohedral crystalline structure. The molecular weight is approximately 382.15 g/mol. It is slightly soluble in water and is relatively stable in air but can react with reducing agents. Terbium oxide is used in various applications due to its unique optical and magnetic properties.

Q: How is Terbium oxide (CAS: 12037-01-3) typically synthesized?

Terbium oxide can be synthesized through the thermal decomposition of terbium(III) nitrate [Tb(NO3)3] or by the reduction of terbium(III) oxide with hydrogen gas. Commonly, the solid-state reaction is used where terbium nitrate is heated in an oxygen atmosphere to form the oxide. The reaction is typically carried out at high temperatures, and the purity and homogeneity of the product can be controlled by adjusting the reaction conditions.

Q: What industries use Terbium oxide (CAS: 12037-01-3)?

Terbium oxide is used in a variety of industries. It is a key component in magnetic materials, especially in the production of magnetic alloys and high-strength steels. It is also used in optical applications, such as in phosphors for cathode ray tubes, LEDs, and laser materials. Additionally, it is employed in the production of sensors and as a dopant in semiconductors.

Q: What precautions should be taken when handling Terbium oxide (CAS: 12037-01-3)?

When handling terbium oxide (CAS: 12037-01-3), ensure to use proper personal protective equipment (PPE), including gloves, goggles, and a lab coat. Store it in a cool, dry place away from chemicals that could react with it. Reactivity with reducing agents and water should be considered. In case of a spill, use appropriate containment and clean up using suitable materials. Refer to the Safety Data Sheet (SDS) for detailed information on handling and storage.
