Calcium copper titanate (CaCu 3Ti 4O 12, CCTO) powder was mixed with boric oxide (B 2O 3) glassy phase up to 8% by weight to prepare the composite ceramics. The effects of B 2O 3 incorporation on the microstructures, electric and dielectric properties of CCTO ceramics have been systematically investigated. Adding B 2O 3 results in both the decrease of the CCTO grain size. These microstructural changes conjointly affect the dielectric constant. In addition, further B 2O 3 increase leads to its aggregation at grain boundaries. Meanwhile, the B 2O 3 addition reduces the nonlinear coefficient and influences the breakdown electric field. © Springer Science+Business Media, LLC 2012.
