The effects of 2ZnO–B2O3 (2ZB) glass addition on the densification and dielectric properties of CaTiO3 (CT) have been investigated. With the 2ZB glass content greater than 20 vol%, the densification temperature can be greatly reduced from 1300°C for pure CT to 875–925°C for CT+2ZB dielectric ceramics. The above result is attributed to a chemical reaction taking place at the interface of 2ZB/CT during firing. The Ca in CT dissolves into 2ZB, forming a new glass of CaO–ZnO–B2O3 at 840–860°C which enhances the densification kinetics of 2ZB+CT dielectric ceramics. For the samples with 20–40 vol% 2ZB, the resulting 2ZB+CT ceramics have a dielectric constant of 60-90 and dielectric loss of less than 0.15% at frequencies below 13 MHz.
