Synthesis and characterization of nanocrystalline Barium Strontium Titanate powder via sol-gel processing

“…2 [20]. A titania-rich phase was observed during synthesis of Ba 0.6 Sr 0.5 TiO 3 powder, calcined at 1,150°C for less than 2 h [13]. It is worth noting that the high surface to volume ratio in nano materials can lead to several interesting properties.…”

“…It is believed that nano-sized materials can offer modified electron sensitive properties [11] and better sinterability [12]. Earlier studies on synthesis of crystalline BST powder resulted in powder of 0.8-2.7 μm [13] using a solid-state reaction route. Selvam and Kumar [14] reported the synthesis of 50 nm BST powder by direct precipitation method.…”

Characterization of non-stoichiometric co-sputtered Ba0.6Sr0.4(Ti1 − x Fe x )1 + x O3 − δ thin films for tunable passive microwave applications

“…Beside the goal to enhance the dielectric properties in BST thin films using acceptor or donor dopants, the dependence of the dielectric characteristics on the microstructure must be taken into account as suggested by Giere et al [15] and Su et al [16]. In the case of screen-printed BST ceramic thick films, it is nearly impossible to investigate the influence of the used dopant sole on dielectric characteristics as it additionally affects the sintering behavior of these ceramics.…”

Sinterability and nonlinear dielectric properties of Ba0.6Sr0.4TiO3 derived from a citrate method

“…1. The calcining temperature required for forming a pure perovskite phase (650 • C) is considerably reduced compared to those (1150-1200 • C) of the conventional solid-state reaction method [16]. This calcining temperature is also comparatively lower than previously reported results regarding synthesizing Ba 0.6 Sr 0.4 TiO 3 powders by the citrate method.…”
