Description

Yttrium Carbonate is an important inorganic salt of the rare earth element yttrium, widely utilized as a high-purity precursor material. Its value lies in providing a controlled source of yttrium oxide (Y₂O₃) for advanced materials synthesis, ensuring consistent performance in demanding applications. This compound is essential for manufacturers and researchers in the electronics, ceramics, and phosphor industries seeking reliable, high-quality raw materials.

Application

• Phosphor Manufacturing: A key precursor for producing yttrium oxide used in red phosphors for cathode ray tubes (CRTs), LEDs, and fluorescent lamps.
• Advanced Ceramics: Serves as a starting material for yttria-stabilized zirconia (YSZ), a critical component in thermal barrier coatings, solid oxide fuel cells, and high-performance structural ceramics.
• Catalyst Preparation: Used in the synthesis of catalysts for petroleum cracking, dehydrogenation, and other organic synthesis processes.
• Glass & Optical Materials: Imparts specific optical properties to glass, used in camera lenses, lasers, and other precision optics.
• Electronic Materials: A source material for thin films and dopants in semiconductors and superconductors.
• Research & Development: Employed in academic and industrial R&D for developing new materials, including nanomaterials and composites.

Quality Control

Our Yttrium Carbonate is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as assay (Y₂O₃ basis), impurity profiles (including other rare earth elements), and physical characteristics. Our quality commitment aligns with industry best practices for high-purity inorganic chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and handling properties.
