Yttrium Oxide

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.

FAQ

Q: Is there any export limitation for the material Y2o3 in China?

A: Since April 2025, our country put Yttrium as dual use item, which is under strict export limitation in China.

But the export licence can be possibly permitted if the end user and end user are not related with military use.

Q: What purity grades are available for Yttrium Oxide?

A: We offer grades from 99.9% (3N) up to 99.999% (5N), tailored to specific application requirements.

Q: Can the particle size be customized for coating applications?

A: Yes, we provide different particle size distributions (nanometer to micrometer ranges) to optimize film uniformity and adhesion.

Q: How should Yttrium Oxide be stored to maintain purity?

A: Store in airtight containers in a dry, cool environment away from moisture and direct sunlight to prevent hygroscopic absorption.

Q: Is this product compliant with RoHS and REACH regulations?

A: Yes, all our Yttrium Oxide products meet international environmental standards for restricted substances.

Q: Can I request a sample for testing?

A: Absolutely! Contact our sales team to arrange a sample shipment and discuss your specific testing parameters.
