Description

Calcium Magnesium Tetrahydroxide is a specialized inorganic compound with a unique mixed-metal hydroxide structure. This material is valued for its dual-source alkaline and buffering properties, offering a synergistic effect compared to single-metal hydroxides. It serves as a critical intermediate and functional additive in several industrial sectors, including environmental remediation, specialty ceramics, and as a precursor for advanced materials. The compound is commercially available under the identifier CAS NO 39445-23-3.

Application

• Flue Gas Desulfurization (FGD): Acts as an effective alkaline sorbent for the removal of sulfur oxides (SOx) from industrial exhaust streams.
• Wastewater Treatment: Used for pH adjustment, heavy metal precipitation, and phosphate removal in industrial and municipal water treatment processes.
• Specialty Ceramics & Glass: Serves as a precursor or additive in the formulation of certain glass ceramics and electronic ceramics, contributing to specific thermal and electrical properties.
• Fire Retardant Formulations: Incorporated into polymers and coatings as a smoke-suppressant and char-forming agent, leveraging its endothermic decomposition.
• Soil Stabilization & Remediation: Applied for pH correction of acidic soils and for immobilizing certain heavy metal contaminants.
• Chemical Synthesis: Used as a solid base catalyst or a reagent in organic synthesis and for the preparation of other mixed metal oxides.

Quality Control

Our Calcium Magnesium Tetrahydroxide is manufactured under a stringent quality management system. Each batch is tested to ensure consistent chemical composition, purity, and physical properties relevant to its industrial applications. While specific grades are available for different uses, all products are accompanied by comprehensive batch documentation. Certificates of Analysis (COA) detailing key parameters are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture and carbon dioxide, which can affect product performance.
