Abstract
MgO-CaO-Al2O3-SiO2 (MCAS) glass synthesized by sol-gel method was used to improve the sintering and dielectric properties of the 0.88Al2O3-0.12TiO2 ceramics. Using MCAS glass as sintering additives, 0.88Al2O3-0.12TiO2 ceramics can be sintered at a relatively low temperature, 1350 °C. The effect of glass additives and post-annealing treatment on the phase compositions and dielectric properties of 0.88Al2O3-0.12TiO2 ceramics is investigated. The decomposition of Al2TiO5, which formed in the sintering process, depends on the MCAS content and time of annealing treatment. Further investigation indicates that the decomposition degree of Al2TiO5 has a strong influence on the microwave dielectric properties of 0.88Al2O3-0.12TiO2 ceramics.
