The Factors which Influence on the Physical Phase of Phosphate Compounds Belonging to NZP Family

Abstract:

A new type of phosphate compound with different chemical composition but the same framework belonging to NaZr₂(PO₄)₃(NZP) family were synthesized by chelating sol-gel route. The factor that influence on the physical phase was investigated in this paper. The physical phase and pore structure of the synthesized powder materials were characterized by X-ray diffraction (XRD) and N₂adsorptiondesorption respectively. The results showed that the crystalline NZP family compounds CaZr₄(PO₄)₆and KZr₂(PO₄)₃which is occupied by Ca²⁺ and K⁺ respectively at lattice site of M_Ican be prepared by sol-gel route followed with calcinations at 700-800°C for 2h, but when the gel precursor of CaZr₄(PO₄)₆was treated by hydrothermal crystallization at 160°C for 24h, the obtained powder was NH₄Zr₂(PO₄)₃ instead of CaZr₄(PO₄)₆.
