Abstract:
Bismuth potassium titanate ((Bi1/2K1/2)TiO3: BKT) powder were prepared using bismuth oxide (Bi2O3), potassium hydrogen carbonate (KHCO3) and titanium oxide (TiO2) raw materials. Barium titanate (BaTiO3: BT) platelike particles oriented along [110] direction were used as template particles. Barium titanate-bismuth potassium titanate (BT-BKT) ceramics had a tetragonal phase at -100 °C. The main composition was fixed to BKT 30 molar% because the Curie temperature (TC) was well above 200 °C at BKT 30 molar%. The orientation of [110]-oriented BT-BKT ceramics (BKT 30 molar%) was 54.6 %.

Background/objectives: Bismuth is commonly used in Helicobacter pylori (H. pylori) eradication therapy. However, few studies have examined the in vitro susceptibility of H. pylori to bismuth. Moreover, the exact mechanism of action of bismuth on H. pylori remains unclear.

We have introduced two different techniques in this paper to investigate the high Tc superconductor BaK BiO₃. The first one is the rigid-ion molecular dynamics model to calculate classical properties of the crystal. This method provides the ionic anisotropic vibrational spectra. It is found that the oxygen modes dominate the vibrational spectrum from 150 cm⁻¹ up to 820 cm⁻¹. An increase in the number of substituted K around an oxygen favors high frequency vibrational modes. We have also determined by experiment IR spectrum. The absorption peaks are between 380 to 880 cm⁻¹. Our experimental and
