- Abstract
- Dolomite-type borate ceramics consisting of CaZrB2O6 were synthesized via a conventional solid-state reaction route; low-temperature sintering was explored using Bi2O3-CuO additives of 1-7 wt% for low-temperature co-fired ceramics applications. For several sintering temperatures, the microwave dielectric properties and chemical resistance of the ceramics were investigated. The CaZrB2O6 ceramics with 3 wt% Bi2O3-CuO addition could be sintered below 925 degrees C, and the microwave dielectric properties of the low-temperature samples were epsilon(r)=10.55, Q x f=87,350 GHz, and tau(f)=+2 ppm/degrees C. The chemical resistance test result showed that both CaZrB2O6- and Bi2O3-CuO-added CaZrB2O6 ceramics were durable in basic solution but were degraded in acid solution.
