Enhanced conductivity and nonlinear voltage–current characteristics of nonstoichiometric BaTiO3 ceramics
Wiley-Blackwell (2011-03-21)The electrical conductivity of both BaO-deficient and TiO2-deficient BaTiO3 ceramics shows nonohmic, low-field characteristics at temperatures >∼200°C in contrast to stoichiometric BaTiO3 for which the electrical conductivity ... -
Photocatalytic degradation of orange II by titania addition to sol-gel glasses
Springer Verlag (2009)Glasses with SiO2-CaO-ZnO-B2O3-K2O-Al2O3 composition modified by addition of titania (3, 5, 12 and 20% w) have been prepared by sol-gel method. The obtained gels were aged, dried and fired at 600ºC/1h in order to stabilise ...
