Description

Zirconium Phosphate is an inorganic compound valued for its ion-exchange properties, thermal stability, and catalytic activity. This material is crucial for applications requiring selective adsorption, proton conductivity, or as a solid acid catalyst. It serves key roles in industries such as chemical manufacturing, water treatment, and advanced material science for developing functional composites and membranes.

Application

• Ion Exchange & Water Treatment: Used as a selective cation exchanger for the removal of heavy metal ions (e.g., lead, cadmium) and radioactive nuclides from wastewater.
• Solid Acid Catalyst: Employed in organic synthesis reactions, including esterification, alkylation, and isomerization, due to its strong surface acidity and reusability.
• Proton-Conducting Membranes: A key component in the fabrication of composite membranes for fuel cells (PEMFCs) to enhance proton conductivity and thermal stability.
• Gas Separation & Sensors: Utilized in composite materials for selective gas separation membranes and as a sensing layer in humidity or gas sensors.
• Dental & Biomedical Composites: Incorporated into dental cements and bioactive materials for its biocompatibility and reinforcement properties.
• Flame Retardant Additive: Acts as a synergistic agent in polymer composites to improve flame retardancy and thermal stability.
• Nuclear Waste Management: Applied in the immobilization and sequestration of radioactive fission products due to its high chemical durability.
• Chromatography: Serves as a stationary phase in ion chromatography for the separation of inorganic and organic ions.

Quality Control

Our Zirconium Phosphate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in purity, particle size, and ion-exchange capacity. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profiles, and physical parameters is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, the material must be stored in a cool, dry place at a controlled room temperature (15-25°C). For long-term storage, consider using a desiccator or an environment with low humidity to prevent moisture absorption and caking.
