Synthesis, doping and electric bulk response of (Bi1/2Na1/2)xBa1-xTiO3 + CaO – based ceramics with positive temperature coefficient of resistivity (PTCR)

Abstract

(Bi1/2Na1/2)xBa1-xTiO3 samples were prepared using the mixed-oxide route; their tetragonal to cubic phase transition temperature increases from 125°C for x = 0 to 190 °C for x = 0.2. (Bi1/2Na1/2)0.10Ba0.90TiO3 (x = 0.10)... [ view full abstract ]
