Abstract

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.
