Description

Aluminum Metaphosphate CAS NO 32823-06-6 is an inorganic phosphate compound of aluminum, valued for its role as a source of both aluminum and phosphate ions in specialized industrial processes. This material is particularly significant for applications requiring controlled reactivity and specific thermal or chemical properties. It is primarily sought by manufacturers in the ceramics, glass, and specialty catalyst industries, as well as for research and development in advanced material science.

Application

• Ceramics and Glass Manufacturing: Acts as a fluxing agent and a source of phosphate to modify melting points, improve thermal shock resistance, and enhance the chemical durability of final products.
• Catalyst and Catalyst Support: Used in the formulation of specialized catalysts for organic synthesis and petrochemical processes, where its surface properties and thermal stability are advantageous.
• Fire Retardant Additives: Incorporated into polymers, coatings, and construction materials to impart flame-retardant characteristics through intumescent or char-forming mechanisms.
• Metal Surface Treatment: Serves as a component in conversion coatings and pretreatments for metals like aluminum and steel to improve corrosion resistance and paint adhesion.
• Specialty Fertilizers and Soil Amendments: Provides a slow-release source of phosphate in agricultural and horticultural applications for specific soil conditions.
• Laboratory Reagent: Employed as a high-purity chemical reagent in analytical chemistry and materials research for synthesizing other phosphate compounds.

Quality Control

Our Aluminum Metaphosphate is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets precise chemical and physical specifications relevant to its intended industrial grade. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your technical requirements.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
