Description

Zirconium(IV) Hydrogenphosphate is an inorganic ion-exchange material and solid acid catalyst of significant industrial interest. Its value lies in its exceptional thermal and chemical stability, high ion-exchange capacity, and proton conductivity. This compound is essential for researchers and manufacturers in the fields of catalysis, advanced ceramics, and environmental technology seeking robust and selective materials.

Application

• Solid Acid Catalyst: Used in organic synthesis reactions such as alkylation, esterification, and isomerization due to its strong surface acidity and reusability.
• Ion-Exchange Material: Employed for the selective removal and recovery of heavy metal ions (e.g., lead, cadmium) and radioactive nuclides from wastewater and process streams.
• Proton Conductor: Investigated for use in intermediate-temperature fuel cells and hydrogen sensors because of its good proton conductivity under certain conditions.
• Ceramic Precursor & Additive: Serves as a precursor for zirconium phosphate-based ceramics and as an additive to modify the properties of other ceramic composites.
• Chromatography & Separation Science: Utilized as a stationary phase or adsorbent for the separation of biological molecules, gases, and ions.
• Gas Sensing & Humidity Sensing: Applied in sensor technologies where its electrical properties change in response to specific gases or moisture levels.
• Nuclear Waste Treatment: Studied for the immobilization and safe containment of specific radioactive waste elements.
• Polymer Composite Filler: Incorporated into polymers to enhance flame retardancy, mechanical strength, and thermal stability.

Quality Control

Our Zirconium(IV) Hydrogenphosphate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in chemical composition, phase purity, ion-exchange capacity, and particle size distribution. A comprehensive Certificate of Analysis (COA) detailing these parameters is provided with every shipment to guarantee 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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide, which can affect performance.
