Product Overview
Yttrium(III) oxide (Y₂O₃) with 99.999% purity (trace metal basis) is a high-performance rare earth oxide engineered for applications demanding ultra-low impurity levels. This fine, white powder exhibits exceptional thermal stability, making it a critical component in advanced ceramic formulations, high-efficiency phosphors, and specialty glass manufacturing. The material’s uniform particle distribution ensures consistent reactivity in solid-state synthesis processes, while its trace metal purity minimizes interference in sensitive analytical or catalytic applications. With a high melting point of 2,425°C and resistance to hydration, this grade is optimized for environments requiring long-term chemical stability. The oxide’s cubic crystal structure provides isotropic properties, enhancing its performance in optical and electronic applications. Rigorous quality control ensures batch-to-batch consistency, with residual metal impurities controlled below 10 ppm. This grade is particularly valued in processes where even trace contaminants could compromise material properties or device performance.
FAQs
1.
What is the typical particle size range for this Yttrium(III) oxide powder?
The powder typically exhibits a particle size distribution between 1-5 microns, though exact specifications may vary slightly by production batch. This range balances reactivity with ease of handling in most applications. 2.
Is this material compatible with standard ceramic processing techniques like slip casting?
Yes, the fine particle size and consistent morphology make it suitable for most ceramic processing methods, including slip casting, pressing, and extrusion when properly dispersed. 3.
What alternatives exist if I need slightly lower purity for cost-sensitive applications?
For applications where 99.999% purity isn’t critical, 99.9% or 99.99% grades are commonly available and may offer cost savings while still maintaining good performance in many technical applications. 4.
How should this material be stored to maintain its purity over time?
Store in a tightly sealed container under inert gas if possible, in a cool, dry environment away from moisture and acidic vapors to prevent any potential degradation or contamination. 5.
Does this product contain any binding agents or anti-caking additives?
No, this is a pure yttrium oxide powder without any additives, binders, or flow agents, ensuring maximum compatibility with sensitive applications where such additives could be problematic.
