Abstract: A series of aluminium-containing α-type hydrated zirconium hydrogen phosphates,Zr1-xAlx(H1+x/2PO4 )2 with x=0-0.06,were hydrothermally synthesized and characterizedby means of X-ray diffraction,differential thermal analysis and thermogravimetric analysis.The proton conductivity,1.2×10-4S·cm-1 at 180℃ was found in Zr0.98Al0.02(H1.01PO4)2·H2O.Humidity-sensing measurements were carried out at 120℃ and 140℃ respectively.Even a limited substitution of Al for Zr can enhance both proton conductivity and humidity sensitivity.

Key words: Aluminium-containing α-type hydrated zirconium hydrogen phosphates, Proton conductivity, Humidity sensing property
