The aim of this study is to develop an application of dielectric ceramics in a dielectric barrier discharge (DBD) plasma reactor to dissociate CO2 to CO and O-2. The fracture strength and dielectric strength of Ca0.7Sr0.3TiO3 were greatly improved by the liquid phase sintering using 0.5 wt.% Li2Si2O5 as a sintering additive. The sintered body was efficient when it was used as a dielectric barrier of a plasma reaction to generate a nonthermal plasma by the DBD. The ratio of CO2 decomposition by the DBD plasma using this Ca0.7Sr0.3TiO3 was much greater than with those using commercial alumina and silica glass barriers. This Ca0.7Sr0.3TiO3 ceramic was sintered using Li2Si2O5 as a sintering additive and used as a dielectric barrier of DBD for the first time. (C) 2004 Elsevier B.V. All rights reserved.
