摘要：

Synopsis. The irreversible water in the interlayer of HLaNb2O7 (HLa), which was removed in the temperature range of 350-400-degrees-C, greatly affected the formation of acidic properties of the HLa. The reversible water removed at lower temperature than 350-degrees-C did not greatly affect the acidic character of the HLa. The relations between the iso-electric points and heat-treatment temperature of the HLa were examined in connection with the acidity.
