Description

Hydroxysodalite is a synthetic zeolite material belonging to the sodalite family, characterized by its aluminosilicate framework structure. This compound is valued for its high thermal stability, uniform pore structure, and selective adsorption properties, making it a critical component in advanced separation and catalysis processes. It is primarily utilized by industries involved in gas purification, petrochemical refining, and the development of novel inorganic materials.

Application

• Gas Separation & Purification: Selective adsorption of carbon dioxide (CO₂), nitrogen (N₂), and other small molecules from gas streams.
• Catalysis & Petrochemicals: Serving as a catalyst support or a shape-selective catalyst in hydrocarbon conversion reactions.
• Ion Exchange: Removal of heavy metal ions or specific anions from industrial wastewater.
• Molecular Sieves: Used in drying and purification processes where controlled pore size is essential.
• Advanced Materials Research: A precursor or template for synthesizing other zeolitic materials and nanocomposites.
• Detergent Builders: Potential use as a co-builder in eco-friendly detergent formulations for water softening.

Quality Control

Our Hydroxysodalite is manufactured under controlled conditions to ensure batch-to-batch consistency and high performance. Quality is verified through a suite of analytical techniques including X-ray diffraction (XRD) for phase purity, scanning electron microscopy (SEM) for particle morphology, and nitrogen adsorption for surface area and pore volume analysis. Certificates of Analysis (COA) detailing specific lot results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, the material should be stored in a cool, dry place at room temperature (15-25°C) with minimal exposure to atmospheric humidity. For long-term storage, consider using desiccants or an inert atmosphere.
