Description

Yttrium is a rare-earth metal with the CAS registry number 7440-65-5, prized for its unique chemical and physical properties that make it a critical component in advanced materials. Its primary value lies in its ability to stabilize crystal structures and impart specific optical and electronic characteristics. This element is essential for manufacturers and researchers in the electronics, phosphor, ceramic, and metallurgical industries, where high-purity materials are non-negotiable for performance and reliability.

Application

• Phosphors and Lighting: A key dopant in yttrium aluminum garnet (YAG) for white LEDs, lasers, and cathode-ray tube displays.
• Electronic Ceramics: Used in yttria-stabilized zirconia (YSZ) for oxygen sensors, solid oxide fuel cells, and thermal barrier coatings.
• Superalloys and Metallurgy: Enhances the oxidation resistance and high-temperature strength of nickel and chromium-based alloys.
• Glass and Optics: Improves the refractive index, durability, and radiation resistance of specialty optical glasses.
• Medical Technology: Employed in yttrium-90 radioisotopes for targeted cancer radiation therapy (radiotherapy).
• Catalysts: Acts as a component in petroleum cracking and polymerization catalysts.
• Research & Development: Serves as a high-purity starting material for synthesizing novel compounds and materials science studies.

Quality Control

Our yttrium products undergo rigorous quality testing to ensure compliance with industry standards. We offer various purity grades, from industrial (99.9%) to high-purity (99.99% and 99.999% / 5N), tailored to specific application requirements. Certificates of Analysis (COA) detailing purity, metallic impurities, and other relevant parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. For long-term storage of high-purity forms, keep under an inert atmosphere such as argon to prevent surface oxidation. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its pyrophoric nature in fine powder form, appropriate safety measures must be observed.
