“…In the previous papers this occurrence was also noticed. Otherwise, some authors [17][18][19] have connected the lowering of T C with grain size decrease and this is in agreement with results obtained in our study.…”

“…Typically micron-sized perovskite-type ceramics (predominantly BaTiO 3 , sometimes doped) have been used as high-k-fillers (Bhattacharya and Tummala 2000; Kakimoto et al 2006, Wu et al 2009Das et al 2008). Quite recently a comprehensive review paper covers the dielectric properties of a huge number of different polymer-ceramiccomposites (Sebastian and Jantunen 2010).…”

A series of commercially available nanosized barium titanates has been investigated with respect to their use as high-k-ceramic filler in polymer based composites with improved dielectric properties. The thermal treatment of the barium titanate powders at 1,000°C causes a significant increase of the composite's permittivity. X-ray diffraction experiments prior and after heat treatment revealed that the barium titanate with smallest particle size and the largest specific surface area possesses the thermodynamically unstable cubic phase. In case of the other investigated barium titanates the crystal lattice is distorted. Thermal treatment induces the phase change into the tetragonal one and crystal lattice relaxation enabling higher permittivity values. Composites with a solid load around 78 wt% with a bimodal particle size distribution show high permittivities around 50 and a low loss factor around 5% suitable for the realization of embedded capacitors via screen printing or tape casting.

“…For BaTiO 3 , the phase transformation from tetragonal to cubic structure occurs at 120~130°C [11] . However, in the case of the BST samples investigated in this study, increasing of Sr content decreases the temperature of phase transformation.…”

Problem statement:The aim of this research was to study the effect of Sr substitution on structure and thermal diffusivity of Ba l-x Sr x TiO 3 ceramic at room temperature. Approach: Structural and thermal diffusivity of Ba 1-x Sr x TiO 3 were studied by performing X-ray diffraction and photoflash measurements. The effects of Sr substitution on the structure and on the thermal diffusivity of Ba 1-x Sr x TiO 3 (0≤x≤1) were investigated. showed a significant effect of structure on thermo-physical property of materials.
