Description

Yttrium is a rare earth metal element with the CAS registry number 10098-91-6, valued for its unique chemical and physical properties that enable advanced technological applications. Its primary commercial importance lies in its role as a critical component in phosphors, ceramics, and high-performance alloys. This material is essential for manufacturers and R&D facilities in the electronics, aerospace, catalysis, and specialized glass industries.

Application

• Phosphors and Display Technology: A key dopant in yttrium oxide (Y₂O₃) for red phosphors in cathode ray tubes (CRTs) and LED lighting, and in yttrium vanadate (YVO₄) for europium-doped red phosphors.
• Advanced Ceramics: Used in yttria-stabilized zirconia (YSZ) for thermal barrier coatings in jet engines, oxygen sensors, and high-durability structural ceramics.
• Superalloys and Metallurgy: Added in small quantities to refine grain structure and improve the oxidation resistance and high-temperature strength of nickel and titanium-based superalloys.
• Glass and Optics: Imparts high refractive index and stability to camera lenses and other optical glasses; used in yttrium aluminum garnet (YAG) crystals for lasers.
• Catalysis: Serves as a catalyst and promoter in petroleum cracking, polymerization reactions, and hydrogenation processes.
• Medical and Research: Utilized in radioisotopes like Yttrium-90 for targeted cancer radiation therapy (radioimmunotherapy) and as a component in various research chemicals.
• Electronic Components: Found in capacitors, superconductors (e.g., YBCO), and other electronic materials where specific dielectric or conductive properties are required.

Quality Control

Our Yttrium is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) detailing purity, metallic impurities, and physical specifications. Quality is verified through advanced analytical techniques including ICP-MS, GD-MS, and combustion analysis for non-metallic impurities. Our production adheres to relevant industry standards, and material can be supplied to meet specific customer requirements for research or industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and easily oxidized nature, yttrium metal must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended storage temperature is 15-25°C. The storage area should be free from moisture and corrosive agents. For long-term storage of high-purity grades, sealing under vacuum or inert gas in ampoules is advised.
