AL9692 Plastic Refractory (Al2O3-SiO2)

Plastic Refractory (Al2O3-SiO2) Description

Plastic Refractory (Al2O3-SiO2) is a composite refractory material composed of alumina (Al2O3) and silica (SiO2) in a powdered form. The controlled particle size distribution enables integration into ceramic matrices used for high-temperature operations. Technical evaluations, such as X-ray diffraction and scanning electron microscopy, assist in monitoring phase composition and microstructural uniformity. This material supports efficient thermal management and structural stability in furnaces and processing equipment.

Plastic Refractory (Al2O3-SiO2) Packing

Plastic Refractory (Al2O3-SiO2) powder is packaged in moisture-resistant, sealed bags that are then placed in corrugated boxes to prevent contamination and physical damage. The packaging design minimises dust dispersion while preserving particle integrity. Storage in a dry, temperature-controlled environment is recommended. Custom labelling, cushioning materials, and anti-contamination measures can be provided to meet specific handling and shipping requirements.

Frequently Asked Questions

Q1: How does the controlled ratio of Al2O3 and SiO2 affect the refractory performance?
A1: The precise ratio governs phase formation and thermal stability. X-ray diffraction analysis confirms the expected ceramic phases, which in turn determine the material’s ability to withstand high temperatures and thermal cycling.

Q2: What processing considerations are critical when using this refractory powder?
A2: Effective dispersion and uniform mixing are essential to avoid localised concentration differences. Controlled heat treatment is also required to promote consistent phase development, ensuring the material performs as expected in high-temperature environments.

Q3: What storage conditions are recommended to maintain the quality of this powdered refractory?
A3: The powder should be stored in sealed containers under controlled humidity and temperature conditions to prevent moisture uptake and maintain particle integrity. This minimises the risk of agglomeration and preserves its physical properties.
