Specification

The Terbium(III) oxide, with the CAS registry number 12036-41-8, is also known as Terbium sesquioxide. It belongs to the product categories of Catalysis and Inorganic Chemistry; Chemical Synthesis; Oxides; Terbium; TerbiumMetal and Ceramic Science. Its EINECS registry number is 234-849-5. This chemical's molecular formula is O₃Tb₂ and molecular weight is 365.85. What's more, both its IUPAC name and systematic name are the same which is called Oxygen(2-); terbium(3+). Terbium(III) oxide is a p-type semiconductor when doped with calcium, and may be prepared by the reduction of Tb₄O₇ in hydrogen at 1300 °C for 24 hours. It is a p-type semiconductor.

Physical properties about Terbium(III) oxide are: (1)#H bond acceptors: 1; (2)#H bond donors: 0; (3)#Freely Rotating Bonds: 0; (4)Polar Surface Area: 0 Å²; (5)Density: 7.9 g cm^-3; (6)Melting point: 2410 °C.

Uses of Terbium oxide: (1) it is used as phosphor and X-ray fluorescent screen; (2) it is a basic oxide and easily dissolved to dilute acids, and then almost colourless terbium salt is formed.

Tb₂O₃ + 6 H⁺ → 2 Tb³⁺ + 3 H₂O
