Abstract

Dielectric ceramics have raised particular interest since they enable pulsed-power systems to achieve high voltage gradient and compact miniaturization. In this work, x wt%Ni 2 O 3 doped Al 2 O 3 -SiO 2 -TiO 2 based dielectric ceramics were prepared using conventional solid-state reaction and the effects of Ni 2 O 3 on the crystal structure, dielectric properties and dielectric breakdown strength were investigated. It was found that with the doping of Ni 2 O 3 , the Al 2 O 3 -SiO 2 -TiO 2 based dielectric ceramics became denser and the distribution of each phase was more uniform. For the composition of x = 2.0, the dielectric breakdown strength was increased into 82.1 kV/mm, more than twice compared with that of the undoped one. In addition, the relationship between the dielectric breakdown strength and the resistance of Al 2 O 3 -SiO 2 -TiO 2 based dielectric ceramics was discussed. The results show that the doping of Ni 2 O 3 is a very feasible way to improve the dielectric breakdown strength and optimize the dielectric properties for the Al 2 O 3 -SiO 2 -TiO 2 based dielectric ceramics.
