Abstract
The sintering behavior and the dielectric properties of CaO–MgO–Al2O3–SiO2 (CMAS) glass and CMAS glass/Al2O3 ceramic composites were studied by the combination of differential scanning calorimetry, X-ray diffraction and scanning electron microscopy as well as dielectric properties measurement. The results demonstrate that the CMAS glass with composition 25CaO-15MgO-12Al2O3-48SiO2 (wt.%) can significantly improve the sintering performance of Al2O3 ceramics, and does not lead to an obvious decrease in the dielectric properties. Low dielectric constant and low dielectric loss were obtained when sintering the CMAS/Al2O3 composites at 1273 K, which demonstrate that it satisfies the requirement of the integrated circuit substrate materials when working at high frequency.
