Notes:
5~15 wt% MgO-CaO-Al2O3-SiO2 (MCAS, fabricated by sol-gel method) glass is used asthe sintering aid of AlN ceramics. The sintering is proceeded from 1350oC~1550oC, scanning electronmicroscope is used to observe the sintered morphologies and X-ray diffraction pattern are used toconfirm the crystal structures. From the SEM observations, as 10wt% and 15wt% MCAS is added,AlN ceramics can be densified at 1500oC and 1450oC, which are much lower than the before studieswere. From the X-ray diffraction patterns, the crystal phases of MCAS-AlN ceramics are AlN, Al2O3,and cordierite phases. In this study, the dielectric characteristics of MCAS-AlN ceramics are alsodeveloped as a function of MCAS content and sintering temperature
