High-Purity Yttrium Oxide for Advanced Ceramic and Optical Coatings

Overview

Boasting purity levels of 99.9%-99.999% (depending on grade), this compound is a cornerstone material in modern high-tech industries. Its unique combination of optical transparency, electrical insulation, and thermal resistance makes it indispensable for applications requiring precision and durability. With a CAS number of 1314-36-9 and a molecular weight of 225.81 g/mol, Yttrium Oxide stands out as a versatile rare-earth oxide with consistent physical properties, including a density of 5.01 g/cm³ and excellent resistance to acid corrosion.

Features

1. Ultra-High Purity: Meticulous purification processes ensure minimal impurity levels, critical for applications where trace contaminants could degrade performance (e.g., optical devices).

2. Optical Transparency: High transmission in the ultraviolet, visible, and infrared spectrums makes it ideal for coating materials in lenses and laser components.

3. Thermal Stability: Maintains structural integrity at elevated temperatures, enabling use in high-temperature environments such as thermal barrier coatings for aerospace engines.

4. Chemical Inertness: Resistant to most acids and alkalis, enhancing its suitability for harsh chemical environments in catalytic converters and corrosion-resistant coatings.

5. Fine Particle Size Distribution: Controllable particle morphology (typically 0.5-5 μm) ensures uniform dispersion in ceramics and composite materials, improving mechanical properties like fracture toughness.

Applications

• Advanced Ceramics: As a sintering additive in zirconia ceramics, Y₂O₃ stabilizes the cubic crystal structure, enhancing strength and thermal shock resistance for industrial cutting tools and medical implants.

• Optical Coatings: Deposited as thin films on optical lenses and mirrors to reduce glare and improve light transmission in cameras, telescopes, and display panels.

• LED Phosphors: Combines with other rare-earth oxides to create red-emitting phosphors in LED lighting, contributing to energy-efficient and color-stable illumination.

• Laser Systems: Used in yttrium-aluminum garnet (YAG) lasers, where it improves thermal conductivity and optical quality, enabling high-power laser applications in manufacturing and medicine.

• Electronics: Serves as an insulator in solid oxide fuel cells (SOFCs) and dielectric layers in capacitors, leveraging its high resistivity and chemical stability.
