| Popis: | A novel microwave dielectric material, the NaSrB5O9 based composite ceramics with low synthetic temperatures of 750–825 °C were prepared via the solid-phase sintering route. All the fabricated ceramics were composed of NaSrB5O9 and SrB2O4. At higher temperatures, some of NaSrB5O9 decomposed to SrB2O4. Dense composite ceramics were obtained under a sintering temperature of 800 °C for 4 h, which exhibited an optimal microwave dielectric performance (er = 5.67, Q × f = 49,824 GHz, τf = −18.28 °C/ppm). The results suggest that NaSrB5O9 based composite ceramics can be promising materials applied in low-temperature co-fired ceramics (LTCC) technology. |
