“…The particle sizes of both BTS 0.105 and BZN mixing powders after the ball milling process, were about 0.5 μm. According to previous studies, the 950 °C-sintered BZN showed a large grain size of about 10 μm [25,26]. The optimum 1100 °C sintering temperature was higher than that of the BZN (950 °C) [26], but much lower than that of the BZN (1380 °C) [25].…”

“…It is obvious that the density change strongly depends on the BZN content, as well as the sintering temperature. It is reported that the sintered BTS 0.105 ceramic has a bulk density of 6.04 g/cm 3 , with a relative density of 98% at 1380 °C [25], while the BZN ceramic has a lower sintering temperature at 950 °C [26]. Thus, the increase of the BZN doping in the BTS 0.105 ceramics could effectively lower the sintering temperature.…”

Recently, tricritical ferroelectrics have been drawn tremendous attention, owing to their ultrahigh dielectric permittivities of up to εr > 5 × 104, and their consideration for prototype materials in the development of high-performance energy storage devices. Nevertheless, such a materials system suffers from the disadvantage of low breakdown strength, which makes its energy density far from the satisfactory level for practical application. In this paper, a material-modification approach has been reported, for improving the dielectric strength for tricritical ferroelectric materials Ba(Ti1−xSnx)O3 (BTS) through doping with Bi1.5ZnNb1.5O7 (BZN) additives. The results suggest that the electric strength has been largely improved in the modified tricritical ferroelectric material (BTSx-yBZN), and the associated energy density reaches Ue = 1.15 J/cm3. Further microstructure investigation indicates that the modified tricritical ferroelectric material exhibits homogenous fine grains with perovskite structure in crystal symmetry, and the BZN may help to form a special structure that could enhance the breakdown strength. The findings may advance the material design and development of high-energy storage materials.

“…into a multilayer ceramic module. The developing LTCC processing requires the creation of new ceramic materials, which possess a high dielectric constant (e r ), small and close to zero values of the temperature coefficient of dielectric constant (s e ), small dielectric losses together with the low sintering temperature (*950°C) and compatibility with Ag electrodes to replace the poor conductivity and high cost Ag-Pd electrode which can greatly reduce the production cost [1][2][3][4].…”

As a promising candidate for thermostable Lowtemperature co-fired ceramic material with NP0 characteristic, (Bi 1.8 Zn 0.2 )(Zn 0.6 Nb 1.4-2x Sn x W x )O 7 (x = 0.00, 0.02, 0.05, 0.10) dielectric ceramics with improved dielectric properties were prepared by conventional mixed oxide route. The effect of the chemical substitution of Sn 4? and W 6? cations on the structure and dielectric properties in this system had been investigated systematically. The Sn 4? and W 6? co-substitution was tentatively introduced in cubicmonoclinic pyrochlores co-existing ceramics and the results showed regular influence on the structure, dielectric properties with the amount of substitution. With the structure evaluation and electrical properties measurement results, the Sn 4? and W 6? substituted Nb 5? in B site showed an effective way to depress the grain growth and the ceramic with fine grains in 1-3 lm that can be obtained at a low sintering temperature of 950°C. Based on these results, small amount of Sn 4? and W 6? substitution was successfully applied to a base ceramic with the electrical properties, which can be a promising candidate for LTCC and multilayer components applications in high frequency and microwave range.
