Multilayer ceramic capacitors (MLCC) are important functional components of electronic information technology. The development of AC MLCC requires low dielectric loss and high AC breakdown voltage. In this paper, Y-Al-Ga-Si co-doped barium titanate ceramics were prepared by conventional solid state method. Microstructures, surface morphology and dielectric properties were investigated by X-ray diffraction, SEM, and LCR analyzer, respectively. Y3+ entered into the lattice of BaTiO3, replaced A-sites and B-sites, suppressed grain growth effectively, and made crystal structure change from tetragonal to pseudo-cubic, which reduced dielectric loss and lowered the Curie peak. The sintering characteristic and permittivity can be improved by the incorporation of Al and Ga. BaTiO3 -0.06Y2O3 - 0.02Ga2O3 -0.01Al2O3 -0.01SiO2 ceramics sintered at 1380°C achieved good dielectric properties: εr= ~2223, tanδ =~1.1% (at 1kHz), ΔC/C25 <~15.26% (from 55°C to 150°C).
