  CaTiO3-LaAlO3 (CTLA) ceramics with Al2O3 nanoparticles were prepared by conventional two-step solid-state reaction, and the sintering behavior and the microwave dielectric proprieties were investigated. The results show that the doping of Al2O3 nanoparticles can promote the growth of uniform grain, increase the density and Q× f value, while it has no obvious influence on the dielectric constant (~45). CTLA ceramics with 0.05 wt% Al2O3 nanoparticles doping, sintered at 1420°C for 4h exhibited the optimal microwave dielectric properties, and CTLA ceramics with 0.2 wt% Al2O3 nanoparticles doping sintered at 1380°C for 4h exhibited the optimal microwave dielectric properties, respectively. A proper increase of Al2O3 nanoparticles content can reduce the sintering temperature... Read More»
