Sealing Compound (Al2O3-SiO2) Packing

The powder is packaged in sealed, moisture-barrier pouches contained within corrugated, anti-static boxes. The packaging is designed to protect against contamination and mechanical damage during transit and storage. It is recommended to store the material in a cool, dry environment with the original sealed package intact. Custom packaging options with specific labelling and compartmentalisation are available upon request.

Frequently Asked Questions

Q1: What measures confirm the powder's particle size distribution?
A1: Particle size distribution is confirmed using laser diffraction analysis, ensuring the powder consistently meets the required range for effective sealing and proper packing density.

Q2: How does the Al2O3 and SiO2 ratio influence sealing performance?
A2: The balanced ratio provides optimised chemical inertness and thermal stability, which enhance the sealing capability against oxidation and thermal-induced stresses in aluminium applications.

Q3: Which storage conditions are recommended to maintain the material’s properties?
A3: The powder should be stored in a cool, dry environment, ideally in its original moisture-sealed packaging, to prevent agglomeration and contamination that could compromise its performance.

Additional Information

Alumina-silica compounds, such as the Sealing Compound (Al2O3-SiO2), are fundamental in applications requiring chemical inertness and thermal endurance. These materials are often selected for their ability to form effective barriers in high-temperature settings and environments prone to oxidation.

The granular nature of these compounds allows for precise control over their physical properties, including particle size distribution and phase composition. This control is critical in industries where reliable sealing and catalyst support are paramount. Advances in powder processing and characterisation continue to enhance the performance attributes required for demanding industrial applications.
