Structure-property relations of ferroelectric BaTiO 3 ceramics containing nano-sized Si 3N 4 particulates

Structure-property relations of ferroelectric BaTiO 3 ceramics containing nano-sized Si 3N 4 particulates

Barium titanate/silicon nitride (BaTiO 3/xSi 3N 4) powder (when x = 0, 0.1, 0.5, 1 and 3 wt%) were prepared by solid-state mixed-oxide method and sintered at 1400°C for 2 h. X-ray diffraction result suggested that tetragonality (c/a) of the BaTiO 3/xSi 3N 4 ceramics increased with increasing content...
