Terbium oxide by Research Lab Fine Chem Industries is a high grade reagent. Also known as terbium (III, IV) oxide and tetraterbium heptaoxide, this is an oxide of terbium. The reagent is available as a dark-brown or black powder which is insoluble in water. It decomposes to Tb2O3 upon melting. Terbium oxide is usually generated by ignition of the oxalate at or the sulfate in air. While this reagent is stable under general conditions, it is incompatible with strong oxidizing reagents. CAS No.: 12037-01-3 Quantity Provided: 5 gm per bottle Molecular formula: Tb4O7 Molecular weight: 747.70 Assay: Minimum 99.9 % Analytical grade reagentTerbium oxide has a variety of applications in chemical and biological sectors. This reagent finds applications in the organic synthesis of various derivative compounds. Terbium oxide reacts with hot concentrated acids to produce terbium(III) salts. It is utilized in the manufacture of glass, optic and ceramic. Terbium oxide nanoparticles are used as analytical reagents for the determination of drugs in food.
