Terbium Sulfate (Tb₂(SO₄)₃·8H₂O) is a white crystalline compound renowned for its role as a critical precursor for terbium-based materials and an efficient catalyst in organic transformations. With a CAS number of 10361-84-9 and a molecular weight of 736.02 g/mol (hydrated form), this compound offers purity levels of 99.9%-99.99% (4N), featuring excellent solubility in water and dilute acids. Its stable trivalent terbium ions (Tb³+) make it indispensable for synthesizing phosphors, magnetic materials, and advanced catalysts, while its low toxicity and thermal stability enhance its utility in both laboratory and industrial settings.
1. High Purity & Low Impurities: Stringent purification processes ensure transition metal contaminants (Fe, Cu, Ni) are <10ppm, critical for maintaining catalytic activity and material homogeneity.
2. Solubility Control: Readily dissolves in water (25 g/100 mL at 20°C) to form clear solutions, enabling precise control over Tb³+ ion concentration in sol-gel and hydrothermal synthesis.
3. Thermal Decomposition Behavior: Releases water of crystallization at 100-200°C and decomposes to Tb₄O₇ above 800°C, serving as a predictable precursor for oxide-basednanomaterials.
4. Lewis Acid Catalysis: Facilitates esterification, transesterification, and C-C bond formation reactions with high turnover rates, reducing reliance on corrosive mineral acids.
5. Hygroscopic Stability: The octahydrate form maintains flowability in ambient humidity (<60% RH), minimizing clumping during storage and handling.
• Catalyst Production: Used in the synthesis of heterogeneous catalysts for biomass conversion, such as converting cellulose to furfural, leveraging Tb³+ ion Lewis acidity to activate functional groups.
• Phosphor Synthesis: A key precursor for Tb³+-doped aluminosilicate phosphors, emitting bright green light (545 nm) for LED lighting and display technologies, ensuring high color rendering index (CRI > 92).
• Magnetic Materials: Incorporating Tb³+ ions into ferrite matrices to enhance magnetocrystalline anisotropy in high-frequency inductors for 5G communication devices, reducing signal loss and improving efficiency.
• Pharmaceutical Intermediates: Catalyzes chiral synthesis reactions in drug manufacturing, such as asymmetric Diels-Alder reactions, enabling enantioselective production of anti-cancer and antiviral compounds.
• Research & Development: Serves as a standard reference material for X-ray diffraction (XRD) and inductively coupled plasma (ICP) analysis, and as a dopant in glass-ceramic composites for optical sensing applications.
Q: Is the anhydrous form of Terbium Sulfate available?
A: Yes, we offer both hydrated (octahydrate) and anhydrous forms; the anhydrous version is recommended for high-temperature sintering processes to avoid moisture-related defects.
Q: What is the optimal temperature for thermal decomposition into Tb₄O₇?
A: Complete decomposition occurs at 850-900°C under air, yielding a fine Tb₄O₇ powder with high surface area (15-20 m²/g) suitable for ceramic doping.
Q: Can Terbium Sulfate be used in electroplating baths?
A: Yes, its water-soluble nature allows integration into electrolyte formulations for depositing terbium-containing alloy coatings with improved corrosion resistance for aerospace fasteners.
Q: Does this product comply with REACH and RoHS regulations?
A: Absolutely, all batches undergo rigorous testing to ensure compliance with international standards for restricted substances (e.g., Pb, Cd, Hg < 1ppm).
Q: What packaging options are available for large-scale orders?
A: We provide 1kg, 5kg, and 25kg packages in moisture-resistant polyethylene bags inside cardboard drums, with custom packaging available for bulk quantities.
