Yttrium Loaded Zirconium Phosphate

Yttrium Zirconium Phosphate (YZP) is an inorganic compound with the chemical formula YPO₄·Zr₃(PO₄)₄. It typically refers to yttrium-doped or modified zirconium phosphate materials, such as Y-doped ZrP or Y-ZrP. These materials are modified by introducing the rare earth element yttrium (Y) into zirconium phosphate (ZrP), resulting in a tetragonal crystal system with a stable structure. This modification aims to optimize the material's structural stability, ionic conductivity, or catalytic performance.


 

 Scope of Application:

Ceramic materials: used to manufacture high performance ceramics.

Catalyst: As a catalyst carrier; the surface yttrium site can enhance the solid acidity and be used for esterification, alkylation and other reactions.

Nuclear waste treatment: used to fix nuclear waste, the radiation stability of yttrium makes it suitable for solidifying highly radioactive nuclides (such as actinides) to form a stable ceramic matrix (similar to yttrium-stable ZrO₂).

Optical materials: used in laser and fluorescence materials.

Gas sensor: The sensitivity of CO, NOₓ and other gases is related to the concentration of yttrium doping, which can be used for environmental monitoring.

Lithium/sodium-ion batteries: Yttrium doping stabilizes the crystal structure of lithium zirconium phosphate (LiZr₂(PO₄)₃), inhibits phase transitions during charging and discharging processes, and extends cycle life. For example, the YₓLi₁₋ₓZr₂₋ₓ(PO₄)₃ system may exhibit higher ionic conductivity.
