摘要：
Lead zirconate titanate (PZT)-fly ash geopolymer pastes composites of 0-3 connectivity were fabricated using 30-50% by volume. The mineralogical compositions of fly ash geopolymer materials were investigated using X-ray diffraction (XRD). The 10mol sodium hydroxide solution and sodium silicate solution at a sodium silicate-to-sodium hydroxide ratio of 0.67 were used to prepare geopolymer pastes. The pastes were cured at 60 degrees C for 2days. The results showed that the dielectric constant of PZT-fly ash geopolymer pastes composites decreased with increasing PZT content at 1 KHz. The dielectric properties of PZT-fly ash geopolymer pastes composites were also found to depend on the frequency.
