Product Overview

This Puratronic™ aluminum oxide (Al₂O₃) is engineered to meet the most demanding purity standards, offering 99.995% metals basis purity with ultra-low trace element contamination. The high-grade material is processed under stringent conditions to ensure consistent particle size distribution and exceptional thermal stability, making it suitable for applications where even minor impurities can compromise results. The powder form provides a high surface area, enhancing reactivity in catalytic and adsorption processes. Its inert nature and resistance to chemical attack further extend its utility in harsh environments, including high-temperature reactions and corrosive media. The material undergoes rigorous quality control, with batch-specific certificates of analysis confirming its composition and performance characteristics. Whether used as a catalyst support, chromatographic medium, or in advanced material synthesis, this aluminum oxide delivers reliability and reproducibility. The Puratronic™ grade is particularly valued in research settings where baseline purity directly impacts experimental outcomes, eliminating variables that could skew data or reduce efficiency.

FAQs

1. What is the typical particle size range for this Puratronic™ aluminum oxide?

The particle size generally falls within a narrow distribution optimized for high surface area applications, though exact specifications may vary by batch. Refer to the certificate of analysis for precise measurements.

2. Can this aluminum oxide be used in high-vacuum applications without outgassing?

Due to its high purity and low moisture content, it exhibits minimal outgassing under vacuum conditions, but pre-treatment (e.g., heating) is recommended for ultra-high-vacuum environments to remove adsorbed species.

3. How does this compare to standard reagent-grade aluminum oxide?

Puratronic™ grade offers significantly lower trace metal impurities (e.g., Fe, Si, Na) compared to reagent-grade, which typically contains higher levels of contaminants that can interfere with sensitive applications.

4. What is the recommended storage condition to maintain its purity?

Store in a tightly sealed container under dry, inert conditions (e.g., desiccator or nitrogen atmosphere) to prevent moisture absorption or contamination from ambient particulates.

5. Is this product compatible with acidic or alkaline solutions?

While aluminum oxide is chemically stable in mild conditions, prolonged exposure to strong acids (e.g., HCl, H₂SO₄) or bases (e.g., NaOH) may lead to dissolution or structural changes. Test compatibility for specific protocols.
