Low temperature sintering and dielectric properties of Ba0.6Sr0.4TiO3–MgO composite ceramics with CaO–B2O3–SiO2 glass addition

Microstructures and dielectric properties of Ba0.4Sr0.6TiO3 ceramics with BaO–TiO2–SiO2 glass–ceramics addition

“…3). Thus, solid particles were fully wetted by liquid phase, which resulted in the decrease of sintering temperature [7][8][9][10][11]. In the rest of this paper, all the samples were prepared at their SSTs.…”

“…Besides a high E b , a large variation of polarization is another key factor, which is related to the dielectric constant to a certain extent [5]. Considering the two factors, the addition of glasses to BST ceramics has widely been investigated for achieving high energy density recently [7][8][9][10][11][12][13][14][15][16].…”

“…Among various systems of glasses, B 2 O 3 -SiO 2 -based glasses, such as BaO-B 2 O 3 -SiO 2 , SrO-B 2 O 3 -SiO 2 , CaO-B 2 O 3 -SiO 2 [8][9][10][11][12], possess higher breakdown strength and well wetting with BST ceramics, which should be effective additives in improving the energy storage density of BST ceramics. However, the dielectric constant of BST ceramics with glass additives was decreased, the dielectric properties of BST ceramics deterioration evidently.…”

Enhanced ferromagnetic properties of low temperature sintering LiZnTi ferrites with Li2O–B2O3–SiO2–CaO–Al2O3 glass addition

“…However, LiZnTi ferrites do not meet the basic requirements with regard to sinterability for LTCC technology since they have relatively high sintering temperature [5][6][7]. The addition of borosilicate glasses is an effective way to decrease the firing temperature in LTCC materials [8][9][10][11][12][13][14]. Those glasses exhibit a softening point of $700°C and have a crucial influence on the viscosity of the melt during the firing as described by the Mauro-Yue-Ellison-Gupta-Allan (MYEGA) equation [15]: log 10 gðTÞ ¼ log 10 g 1 þ ð12 À log 10 g 1 Þ Tg T exp m 12Àlog 10 g 1 À 1 h Tg T À 1 i ; where T g is the glass-transition temperature, defined by log 10 gðT g Þ ¼ 10 12 Pa s [16], m is the liquid fragility index, defined by m ¼ @log 10 gðTÞ @ðTg=TÞ T¼Tg [17].…”

Energy storage properties in Ba 0.4 Sr 0.6 TiO 3 ceramics with addition of semi-conductive BaO–B 2 O 3 –SiO 2 –Na 2 CO 3 –K 2 CO 3 glass

“…Fortunately, benefited with doping materials, such as glasses, the performance of the Ba x Sr 1Àx TiO 3 ceramics can be substantially improved [10][11][12][13][14][15]. It was reported that the BDS values of Ba x Sr 1Àx TiO 3 ceramics can reach as high as 239, 164 and 135 kV/cm by adopting BaO-B 2 O 3 -SiO 2 [10], BaO-Al 2 O 3 -B 2 O 3 -SiO 2 [14], and SrO-B 2 O 3 -SiO 2 [15] glass as additives, respectively.…”
