Synthesis and characterization of Barium Strontium Titanate (BST) micro/nanostructures prepared by improved methods
Nowadays various methods are presented for synthesis of barium strontium titanate (BST) nanopowders with different morphology and properties. Each of these (BST)s has got individual characterization that makes it suitable for a special application. Every method has a special quality, causes it to have preference over the other methods. Low processing temperature is a desired point which most of...

Stoichiometric tetragonal Bal-xSrxTiO3 (x = 0.23) nanopowders were prepared by stearic acid gel(SAG) method using barium stearate, strontium stearate, tetrabutyl titanate as Ba, Sr, Ti sourcesand stearic acid as complexing reagent. Thermal analysis including differential thermogravimetric(DTG) and TG, Fourier transform infrared spectrometry (FTIR), X-ray diffraction (XRD) andtransmission electr...
متن کاملSynthesis and Characterization of PbTiO3 Nanopowders by Citric Acid Gel Method
High purity lead titanate nanopowders in tetragonal form have been successfully prepared bycitric acid gel method using lead nitrate and tetra-n-butyl titanate as Pb and Ti sourcesrespectively and citric acid as complexing reagent. The precursors were calcined at varioustemperatures ranging from 450 °C to 600 °C for 2 h. Fourier Transform InfraredSpectroscopy (FT-IR), X-ray diffraction (XRD) an...
متن کاملDc and Ac Electrical Properties of Ptc Barium Titanate Ceramics
The dc and ac electrical properties of PTC barium titanate ceramics were measured in the temperature range from 30 to 450°C. The Heywang's model alone is not sufficient to perform a quantitative analysis of the results. The heterogeneity of the system is taken into account.
