Description

Magadiite (Si7Na(Oh)O14.5H2O) is a naturally occurring hydrous sodium silicate mineral with a unique layered structure. This material is valued for its high cation exchange capacity and its utility as a precursor for synthesizing advanced microporous and mesoporous materials. It serves as a critical raw material and catalyst support in several high-tech industrial sectors, including petrochemical refining, environmental remediation, and advanced material science.

Application

• Catalyst & Catalyst Support: Used as a precursor or direct support for catalysts in petroleum cracking and other organic synthesis reactions.
• Ion Exchange & Adsorption: Employed in water treatment and purification processes to remove heavy metal ions and other contaminants due to its high exchange capacity.
• Nanocomposite Synthesis: Acts as a starting material or template for creating pillared clays, layered double hydroxides (LDHs), and other nanostructured composites.
• Advanced Material Precursor: Utilized in the synthesis of zeolites, mesoporous silicas (e.g., MCM-41), and other porous materials with tailored pore structures.
• Rheology Modifier: Can function as a thickening or gelling agent in specialized coatings, drilling fluids, and ceramic formulations.
• Research & Development: Serves as a model compound in geochemical studies and material science research investigating layered silicate properties.

Quality Control

Our Magadiite is produced and handled under a strict quality management system. Each batch is tested to ensure consistency in chemical composition, crystallinity, and particle size distribution. A comprehensive Certificate of Analysis (COA) detailing purity, identification, and physical parameters is provided with every shipment to guarantee it meets your specific research or industrial application requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry place at room temperature (15-25°C/59-77°F) with low humidity. For long-term storage, consider using a desiccator or inert atmosphere to prevent moisture uptake and maintain product integrity.
