Products Description of Zirconium(IV) Hydrogen Phosphate CAS#13772-29-7
Zirconium phosphate (ZrP), also known as zirconium hydrogen phosphate, is a fine phosphorus-based chemical product with the chemical formula Zr(HPO₄)₂·2H₂O. It appears as a white powder with an acidic pH and exhibits stable chemical properties.
Zirconium phosphate is insoluble in water and general organic solvents. It offers good resistance to both acids and alkalis, along with high thermal stability and mechanical strength. These properties make it widely used as a solid lubricant in self-lubricating composite materials.
Due to its large specific surface area and good ion-exchange properties, zirconium phosphate can also be used as an effective adsorption material. It has applications in a variety of fields, including environmental protection, medicine, advanced materials, and catalysis.
Product Application of Zirconium(IV) Hydrogen Phosphate CAS#13772-29-7
Zirconium phosphate is an inorganic carrier with ion-exchange properties and is widely used as an ion exchanger, particularly as a carrier for silver-loaded antibacterial agents.
In the domestic zirconium phosphate antibacterial agent market, silver-based zirconium phosphate products mainly feature two crystal structures: layered zirconium phosphate and cubic zirconium phosphate.
Layered zirconium phosphate typically has an α-ZrP configuration, with ion-exchange sites located within the interlayer spaces. The hydroxyl groups present in these interlayer regions serve as active centers and can participate in ion-exchange processes.
Cubic zirconium phosphate has a hexahedral crystal structure, in which ion exchange mainly occurs through micropores located on the surface of the hexahedral structure.
