Abstract
Sintering behavior and dielectric performance of yttria/silica‐coated BaTiO 3 powders (YSBT) with the addition of Mn–Si–O glass (0–0.5 wt%) were investigated. The sample made with YSBT powder of 0.35 μm average particle size was fully sintered at 1300°C in 1 h, and further lowered to 1200°C with 0.2 wt% glass addition. The average grain size and secondary phases of sintered BaTiO 3 were characterized with XRD and TEM analyses. The resulted dielectric properties, dielectric constant, dielectric loss, and temperature‐capacitance characteristic, have been examined in air or reduced atmosphere, and discussed corresponding to microstructural features.
