Sintering behavior and dielectric properties of SrB2Si2O8 ceramics

In this paper, the sintering behavior of the SrB2Si2O8 ceramics based on the SrO–B2O3–SiO2 composition has been investigated. The influence of the BaO addition to the SrO–B2O3–SiO2 ceramics on the sintering behavior has been also examined. It shows that, due to the low-meting characteristics of the SrO–B2O3 binary composition, the SrB2Si2O8 ceramics with peculiar dielectric properties can easily prepared by the introduction of SiO2 to the SrO–B2O3 binary compositions at a sintering temperature of 950 °C. Additionally, the introduction of BaO to SrO–B2O3–SiO2 ceramics has an obvious effect on the sintering behavior of the SrB2Si2O8 ceramics. Also, the dielectric properties of the SrB2Si2O8 ceramics are correlative to the phase compositions and the microstructures.
